Data management

Upload data

Upload data through rest interface using Shapefile/GeoTIFF or GeoPackage

Store in PostGIS

Store data in PostGIS through direct connection with PostGIS database

Reference data

Publish data in GeoServer by referencing data from Oracle spatial database

Managed Workspace

When this option is turned on, Bridge will manage about the workspaces in GeoServer by enforcing a one to one relationship between ESRI map projects (.mxd) and workspaces. When publishing a mapdocument_a.mxd with layer layer_a and layer_b, bridge will create a new workspace mapdocument_a in GeoServer and publish both layers in this workspace.

PostGIS connection

Configure a PostGIS connection to publish your map data to PostGIS. The PostGIS connection can be used in three different publish scenarios:

  1. Publish only map data to PostGIS

  2. Publish map layers to GeoServer and store data directly in PostGIS using a direct database connection

  3. Publish map layers to MapServer and store data directly in PostGIS using a direct database connection

MapServer connection

Configure a MapServer connection to publish your maps from ArcGIS Desktop® to MapServer. When using Mapserver 4 Windows choose Use default MS4W values to fill out the MapServer details form.

MapServer Server Configuration

MapServer server configuration

In the Uploading data tab configure how Bridge stores data for your MapServer connection. Choose Local path to store the files in a location on the local file system. Choose FTP service to transmit the files over FTP to the MapServer server.

MapServer data connection

Managed workspace

Bridge currently does not offer functionality to deactivate managed workspace for Mapserver. This means that each ArcMap project is published as a single service endpoint (mapfile).

MapServer data connection

In the Data settings tab enable Store data in PG to have Bridge store vector data in a PostGIS database. When enabled you can choose a connection from the available PostGIS connections. To create a new PostGIS connection see PostGIS connection.

Copy fonts to MapServer

Bridge can be configured to copy the fonts used in your symbology to MapServer. See CopyFontsMapServer for more details.

MapCache configuration

With the MapCache module of GeoCat Bridge you can configure a MapCache instance to serve map tiles. The MapCache module does not manage the seeding of map tiles.

MapCache requirements

With the MapCache module Bridge can configure one Mapcache instance per MapServer. This means that all the mapfiles with share one endpoint for the tile cache. To have Mapcache reload the configuration after each change to the configuration file it is required to have MapCache installed with FastCGI.

Installation instructions for MapCache with FastCGI on Ubuntu 14.04:

For MapCache to auto refresh the configuration MapCache with FastCGI is a prerequisite. To install Mapcache with FastCGI you need to install the following packages:

  • mapcache-cgi (version 1.2.1-2)

  • libapache2-mod-fcgid (version 1:2.3.9-1)

Install with:

sudo apt-get install mapcache-cgi libapache2-mod-fcgi

Enable the FastCGI apache module with:

sudo a2enmod fcgid

Add the following snippet to the Apache virtual host (located on Ubuntu on /etc/apache2/sites-enabled/000-default.conf) to enable the MapCache service:

<IfModule mod_fcgid.c>
FcgidIOTimeout 120
FcgidInitialEnv "MAPCACHE_CONFIG_FILE" "/home/user/ftp/projects/mapcache.xml"
<Location /map.fcgi>
Order Allow,Deny
Allow from all
SetHandler fcgid-script
ScriptAlias /map.fcgi "/usr/lib/cgi-bin/mapcache"

Restart the Apache service:

sudo apachectl restart

Check whether MapCache is running correctly by visiting the following url in your browser (assuming that the Mapcache configuration file has the demo service enabled): http://localhost/map.fcgi/demo

FTP setup

When republishing a Mapcache for a layer Bridge will delete the cached tiles from the temp folder path for that layer by FTP. This means that the temp folder needs to be accessible and writable by the FTP user. Therefore the Mapcache FTP configuration consists of two fields:

  • Path to tmp folder –> Absolute path to tmp folder on server

  • FTP path to tmp folder –> Path to tmp folder that is accessible for ftp user

In the scenario that FTP user is not allowed to venture outside of its home folder it is advised to mount the Mapcache temp folder in the FTP users home directory like this:

mkdir /home/user/ftp/mapcache-temp
mount --bind /tmp/mapcache/ /home/user/ftp/mapcache-temp

For the configuration of the Mapcache this means the following values:

  • Path to tmp folder –> /tmp/mapcache

  • FTP path to tmp folder –> /mapcache-temp

In the scenario that the FTP user has direct access to the Mapcache temp folder the same values can be supplied:

  • Path to tmp folder –> /tmp/mapcache

  • FTP path to tmp folder –> /tmp/mapcache

File permissions

MapCache needs sufficient permissions to write the tiles to the temporary folder. Therefore the temporary MapCache folder should be owned by the www-data user and www-data group.

sudo chown www-data:www-data /tmp/mapcache

The FTP user also needs permissions to delete tiles from the temporary folder. SO the FTP users needs to be added to the www-data group and the File Acces Control list for the MapCache folder needs to be modified, so all files created in the MapCache temp folder are writable by group members.

usermod -g www-data user
sudo chmod g+s /tmp/mapcache/
sudo setfacl -d -m g::rwx /tmp/mapcache/
sudo setfacl -d -m o::rx /tmp/mapcache/

The MapCache configuration file

The MapCache configuration file generated by Bridge will look like this:

<?xml version="1.0" encoding="utf-16"?>
<cache name="disk" type="disk">
  <symlink_blank />
<service type="wmts" enabled="true" />
<service type="tms" enabled="true" />
<service type="kml" enabled="true" />
<service type="gmaps" enabled="true" />
<service type="ve" enabled="true" />
<service type="mapguide" enabled="true" />
<service type="demo" enabled="true" />
<service type="wms" enabled="true">
<source name="mxdname:layername" type="wms">
<tileset name="mxdname:layername">
  <metatile>5 5</metatile>
    <title />
    <abstract />

Any new layers published will be inserted in the MapCache configuration file. By default for each layer a tile cache is configured for the following projections:

  • epsg:4326

  • epsg:3857

  • epsg:900913

To generate a tile cache for a different projection you will need to publish your layer to MapServer with that projection enabled and insert a tiling definition scheme in the MapCache configuration file. It should be inserted as a direct child of the Mapcache element. For instance a tiling scheme for RD_NEW (epsg:28992) is:

<grid name="rd">
        <!--extent>98827,469579,142183,502096</extent--> <!-- Extent adam -->
        <resolutions>3440.64 1720.32 860.16 430.08 215.04 107.52 53.76 26.88 13.44 6.72 3.36 1.68 0.84 0.42 0.21</resolutions>
        <size>256 256</size>

After inserting the tiling scheme in the MapCache configuration file, all future published layers will have a tile cache configured for that projection.

Mapcache configuration in Bridge

When the MapCache server is running at http://host/map.fcgi, the temp directory is /tmp/mapcache and this folder is accessible for the FTP user through /home/user/ftp/mapcache-temp, configure the MapCache connection in the PostGIS tab of the MapServer connection like this, but replace the correct values for user and host:

MapServer MapCache configuration

Import Server Connections

Bridge can import server connections from a previous Bridge 2 installation. Click on images/level-down.png to open the import server connections form. When Bridge detects a Bridge 2 configuration database on your machine, Bridge will display the following notice. Otherwise click the Folder button to browse to the Bridge 2 configuration database with the server connections to import (filename arcgis_publisher.s3db and should be located in the users LocalApplicationData directory C:\Users\<USER>\AppData\Local\GeoCat\Bridge 2).
