JMap Server can read CSV files or any text file with separated values that contain x and y coordinates. These coordinates can be used for layers of points. The first row must contain the field names. The allowed separators are commas (,), semicolons (;) and tab characters. Text fields may or may not be inside double quotes. X and Y coordinates must be numeric values.
JMap Server can read ESRI File geodatabases as a spatial data source.
JMap Server can read ADF and E00 files as a spatial data source. These files are normally produced by ESRI’s Arc/Info software.
JMap Server can read DGN version 7 and 8 files as a spatial data source. Select the data source type that is appropriate for your DGN files’ version. DGN files are generally produced by Bentley MicroStation.
DGN files are often paired with a database of attributes. This can be an MS Access database or any other database system. If the DGN files have attributes stored in a separate database, you must first configure a database connection pool for that database before proceeding. See Creating Databases for more information on database connection configuration.
Vector data sources are used to access vector spatial data (points, lines, polygons, etc.). See the following sections for information on the various types of vector data sources that are supported.
When configuring a vector spatial data source, you need to configure attributes for the data source. All available attributes are listed in a table. By default, all attributes are included but some attributes can be excluded, in which case they will be completely ignored by JMap Server. It is also possible to specify for which attributes JMap Server should create an index in order to optimize performances when queries are performed on these attributes (if no index is used, this will not affect map download and display times). These indexes are used when performing attribute queries on these fields.
This section also contains settings to configure external attributes. See External Attributes for more details on this topic.
JMap Server can read EDIGEO files as spatial data sources.
JMap Server can read DWG and DXF files produced by Autodesk Autocad versions 12 to 2018 as a spatial data source. Block attributes are read and converted into element attributes.
GPX is an XML-based GPS data exchange format. JMap Server can read GPX files as a spatial data source.
JMap Server can read MID/MIF files as a spatial data source. These files are generally produced by MapInfo applications.
JMap Server can read photo files (360 or normal) in JPEG format as a source of spatial data. These photos can be viewed in JMap Pro and JMap NG applications from point layers associated with this type of data source.
JMap Server reads all image files in the specified directory. Files that are not images or image files without spatial information (latitude and longitude) are ignored.
From each file, JMap Server reads the metadata (latitude, longitude and other information) and writes them to a JMap Spatial table. Coordinates (latitude and longitude) define a point and other metadata are attributes of the point. Direction data can be used, for example, to apply a rotation to symbols that represent the points. 360 photos are processed as normal photos.
JMap Server can read TAB files as spatial data sources. These files are usually produced with MapInfo applications.
JMap Server can read shape files as a spatial data source. They are generally produced by ESRI applications.
JMap Server can read Enterprise geodatabases that use the ArcSDE service (ArcGIS version 10.1 and earlier) to extract spatial and attribute data to be used as a spatial data source. The connection to the ArcSDE service must already be configured. See for more information.
There is a special attribute configuration option that is available only with ArcSDE data sources that have attribute domains.
In order for JMap to use ArcSDE attribute domains, they must be exported into database tables that JMap can understand. There is a tool that plugs into ArcCatalog to create such tables. Please contact K2 Geospatial for more information on this.
JMap Server can read KML files as spatial data sources.
JMap Server can read GML files as a spatial data source. GML files must be paired with schema files (.XSD). If a GML file contains instances of more than one feature type, only one of those types can be chosen as the base type for the data source. JMap can read GML files of versions 2.x and 3.x.
JMap has its own storage format for annotations in database tables. If you have any annotations in this format, JMap Server can use them as a spatial data source. Annotation tables in JMap format have a certain number of required fields, as explained in the table below. An SQL query must be provided. The query will be executed to read the data and it can access more than one table at a time.
The database connection must already be configured. Refer to the section for more details on this topic.
JMap Server can read Industry Foundation Classes (IFC) files as a spatial data source. IFC is the standard exchange format commonly used by software for building information modeling (BIM).

Write
No
Parameters
Selected files
Select one or more DWG or DXF files to read. If selecting more than one file, all files must have the same list of attributes and geometries must be of the same type.
Source
The Autocad file contains a model space and a paper space. The paper space contains additional elements that are intended for printing. Select the space to use in order for the data to be read by JMap (typically the model space).
Line and polygon options
No conversion: No conversion will be done. Convert closed lines to polygons: Closed line objects will be read as polygons by JMap. Convert polygons to lines: Polygon objects will be read as lines by JMap.
Block reference options
No conversion: No conversion will be done. The different types of objects (lines, polygons, …) will be treated separately by JMap.

JMap Spatial is the format used to store JMap’s spatial and descriptive data. It is based on the WKB format (http://en.wikipedia.org/wiki/Well-known_binary).
An existing JMap Spatial table may be used as a spatial data source or a new one can be created to receive data.
Click on Add table to create a new table in JMap Spatial format. You can also select an existing table and click on Edit table to change its name or structure. When creating or editing a table, you can add new fields to the table in the User Attributes tab by clicking on and remove fields by clicking on . Note that there are other fields in the table displayed on the System Attributes tab. These include geometry fields (vary according to geometry type), spatial index fields, and so on. These fields are created and populated automatically by JMap.
Once the table has been created or modified, it can be used for the spatial data source.
JMap Server can connect to ArcGIS Server and ArcGIS Online REST services to access vector data published by this type of service. Geometries and attributes are available, but the other information (styles, scales…) is ignored and must be configured in the layers of the JMap project.
Note that it is also possible to create a JMap project by importing an existing layer configuration from an ArcGIS REST service. Refer to Creating projects for more information.
JMap Server can read Enterprise geodatabases from ESRI (ArcGIS 10.0 and later, JMap Server validates the EGDB version) to extract spatial and attribute data to be used as a spatial data source. The connection to the database must already be configured. See Creating Databases for more information.
The spatial data source supports value domains. Relationships defined in the enterprise geodatabase (EGDB) are also supported, but can only be exploited by using external tools.
The data source attributes will correspond to the table columns. To associate the data from other tables, a view can be created in the database and then be configured as a layer in JMap. The data source attributes will then correspond to the columns returned by the view.
JMap Server may use a vector spatial data source that comes from another JMap Server instance. To enable this, you must start by configuring a connection towards the other JMap Server. Refer to JMap Server to JMap Server Connections for more information.
JMap Server can connect to any relational database to extract X and Y coordinates that can be used as a spatial data source to create layers of points. The database must contain at least coordinate fields (numeric values) and a field with unique integer values to be used as element identifiers. An SQL query must be provided. This query will be executed to read the data and it can access one or many tables at the same time.
The connection to the database must already be configured. See Creating Databases for more information.
JMap Server can connect to MongoDB to extract spatial data and attributes to be used as a spatial data source.
NoSQL database systems such as MongoDB are widely used in cloud applications. They have made it possible to solve important problems that traditional SQL database management systems have encountered (rigid schemas, lack of scalability, limited performance).
You need to connect to a MongoDB system (https://www.mongodb.com/en) stored locally or in the cloud. MongoDB offers a local application, MongoDB Compass and a web application, MongoDB Atlas that allow you to access data.
The data or documents are organized in collections (analogous to relational database tables) stored in databases that integrate “clusters” (MongoDB deployments). The clusters are organized into projects.
Data loading can take some time due to the lack of structure of the data collections.
JMap Server can connect to Oracle Spatial or Locator databases to extract spatial data and attributes to be used as a spatial data source. The only special requirement is the presence of a numeric column with unique integer values to be used as element identifiers. An SQL query must be provided. This query will be executed to read the data and it can access one or many tables at the same time.
The connection to the database must already be configured. See Creating Databases for more information.
JMap Server can read ESRI Personal geodatabases to extract spatial and attribute data to be used as a spatial data source. This format uses Microsoft Access files to store the data. The connection to the Access database must already be configured using the MS Access driver. See Creating Databases for more information on this topic.
JMap Server can connect to services complying with the OGC API Features standard (https://ogcapi.ogc.org/features/) to use them as spatial data source. This new OGC standard replaces the WFS services standard.
OGC API Features provides APIs for creating, modifying, and querying “features” (real world elements or entities) on the web. The OGC API Features is made up of several parts, each of which is a separate standard. Part 1, the “core”, specifies the basic capabilities and is limited to the recovery of features where the geometries are represented in the WGS 84 longitude/latitude coordinate reference system. Part 2 specifies capabilities for extracting features whose geometries are represented in all other coordinate reference systems. Part 3, which is in the development phase, concerns data filtering as well as queries using the Common Query Language (CQL). Additional capabilities that meet more advanced needs will be specified in additional parts: support for creating and modifying features, more complex data models, multiple data sets, and collection hierarchies (https://www.ogc.org/standards/ogcapi-features).
JMap 7 Kathmandu implements part 1 of the standard, which provides access to spatial data (entities or features) organized in collections. The data is sent in HTML or GeoJSON format (https://ogcapi.ogc.org/features/overview.html).
JMap Server can connect to MySQL Spatial databases to extract spatial data and attributes to be used as a spatial data source. The only special requirement is the presence of a numeric column with unique integer values to use as element identifiers. An SQL query must be provided. This query will be executed to read the data and it can access one or many tables at the same time.
The connection to the database must be already configured. See Creating Databases for more information on this topic.
JMap Server can read GeoJSON files as a spatial data source.
JMap Server can connect to PostGIS databases to extract spatial data and attributes that can be used as a spatial data source. The only special requirement is the presence of a numeric column with unique integer values to be used as element identifiers. An SQL query must be provided. This query will be executed to read the data and it can access one or many tables at the same time.
The connection to the database must be already configured. See Creating Databases for more information.
Web Feature Service (WFS) is a standard proposed by the Open Geospatial Consortium that defines how client applications should request map vector data and attributes from a WFS compatible server. The protocol used is HTTP and the data returned is typically in Geography Markup Language (GML). WFS servers publish their capabilities in an XML document that specifies the types of requests supported and provides a description of available features.
JMap Server can read data from WFS servers versions 1.0.0 and 1.1.0 to be used as a spatial data source.
JMap Server can connect to databases containing geometries that have been coded according to WKB and WKT standards (http://en.wikipedia.org/wiki/Well-known_text).
In addition to the column containing the geometry, you must have a number column with unique integer values used as element identifiers. There must also be 4 columns containing the values of minimum bounding rectangles (MBR).
An SQL query must be provided. The query will be launched to read the data and it can access more than one table at a time.
The connection to the database must already be configured. Refer to the section Creating Databases for more information on this topic.
JMap Server can connect to Microsoft SQLServer Spatial databases to extract spatial data and attributes that can be used as a spatial data source. The only special requirement is the presence of a numeric column with unique integer values to be used as element identifiers. An SQL query must be provided. This query will be executed to read the data and it can access one or many tables at the same time.
The connection to the database must be already configured. See for more information.
Note: The projection system selected for the spatial data source must exactly match the spatial reference identifier (SRID, e.g. EPSG) of the elements of the table, for the elements to be displayed.
