WMS service management

 

WMS service management

CartoDruid allows you to configure layers that query WMS services.

You will be able to build a catalog of services that you will use to add Raster layers to your project.

Índice

WMS Catalog

To access the WMS catalog of our project, we will perform the following actions:

  1. We display the table of contents (TOC) of the application by clicking on the CartoDruid icon and click on the add layer button that is in the lower left corner of the TOC.
  2. Select the option «Raster Layer».
  3. Select the option «WMS Layer».

The actions that we can perform on the WMS catalog will be:

  1. Create a New Group that we will use to group different services.
  2. Create a New WMS Service.
  3. Actions of each service:
    • Load: It will add a raster layer to your project with the data resulting from the request to the WMS service.

    • Edit: It will open a dialog where you can modify the parameters of the WMS request.

      >
       
    • Delete: It will delete the WMS service from our catalog.

       
       
    • Move to: It will move the WMS service to another group in the catalog.

       

WMS Group

Clicking on the icon will open the following dialog:

We introduce the name of the new group and press accept to return to the «WMS Catalog» screen with the new group created.

New WMS Service

Clicking on the icon will open the following dialog:

We introduce the parameters of the WMS request: name, description, path to the on-line service,... We press accept to return to the «WMS Catalog» screen with the new service added to the Default group. At this point we will be asked if we want to add the layer to the TOC. From the option Move to ... of the service we will move it to the group to which the service will belong.

Manual configuration WMS Catalog

For each project that we have configured in CartoDruid, there will be a wmsRepository.«project_id».json file in the cartodroid/config / folder. This file stores the WMS catalog defined and configured for the project.

By default with the CartoDruid installation a wmsRepository.json file is included without content to work with the basic project.

If you have a list of WMS that you want to use in your project, you can configure it by hand by modifying said file.

An example of this file:

[
  {
    "group": "Default",
    "type": "",
    "url": "",
    "name": "",
    "description": "",
    "rangeMin": "",
    "rangeMax": "",
    "invertAxisOrientation": "N"
  },
  {
    "group": "IDECyL",
    "type": "WMS",
    "url": "https://idecyl.jcyl.es/geoserver/au/wms",
