AltiProfil for Lizmap

Description

This Lizmap module allows you to create topographic profile, either from a raster table stored in PostGIS or an online API such as French IGN data provider.

Installation

This module is compatible with Lizmap Web Client 3.4 and higher. You should install it with Composer. If you can't, you must follow the manual installation part.

With Composer

• In lizmap/my-packages, create the file composer.json if it doesn't exist by copying the file composer.json.dist. Then launch Composer by specifying the module name to install.

cp -n lizmap/my-packages/composer.json.dist lizmap/my-packages/composer.json
composer require --working-dir=lizmap/my-packages "arno974/lizmap-altiprofil"

• Then go in lizmap/install/ and execute some scripts :

If you are using Lizmap Web Client 3.6 and higher, launch first :

php configurator.php altiProfil
php configurator.php altiProfilAdmin

• Then, whatever the version of Lizmap, launch installation scripts :

php installer.php
./clean_vartmp.sh
./set_rights.sh

Go to the configuration part.

Manual installation

• Download the ZIP from the GitHub release page.
• Extract the zip and copy directories AltiProfil, and AltiProfilAdmin in folder lizmap/lizmap-module/
• Modules need to be enabled in Lizmap by editing the configuration file lizmap/var/config.

For Lizmap 3.4 or Lizmap 3.5, add in the file lizmap/var/config/localconfig.ini.php, in the [module] section, the reference to these 2 modules. Do not remove references to other modules in this section.

[modules]

altiProfil.access=2
altiProfilAdmin.access=2

For Lizmap 3.6 or higher, don't modify lizmap/var/config/localconfig.ini.php, launch this command instead:

php lizmap/install/configurator.php altiProfil
php lizmap/install/configurator.php altiProfilAdmin

• Then for any version of Lizmap, launch the installation of the modules with

php lizmap/install/installer.php
lizmap/install/clean_vartmp.sh
lizmap/install/set_rights.sh

Configuration

It's necessary to go in the administration panel of Lizmap Web Client to set up the module.

This configuration will create or edit the file lizmap/var/config/altiProfil.ini.php, which might contain for instance :

[altiProfil]
altisource=Source of data

;if database
altiProfileProvider=database
altiProfileTable=dem_table
srid=3957
; profilUnit = PERCENT or DEGREES - unit for the profil
profilUnit= PERCENT
; dock panel = dock or minidock or rightdock
dock=dock
altiresolution=DEM resolution

;if IGN French data provider
;altiProfileProvider= ign
ignServiceKey=votre clé IGN / your IGN key
ignServiceUrl=https://wxs.ign.fr/

You can specify your data source. Depending on your datasource, some extra configuration might be needed.

Database

altiProfileProvider=database

IGN French provider

altiProfileProvider=ign

Override the configuration for a single project

For every project published in Lizmap, for instance my_project.qgs, you can add a new file with extension .alti at the end of the file. In our example, it would be my_project.qgs.alti.

This file allows you to override some settings.

For instance

[altiProfil]
altisource="DEM Paris high-resolution"
altiProfileTable=srtm_paris_high_resolution
srid=3857

Use-case from a database

To use this module with a database, you should connect to a raster table having a DEM. You need to add in the file profiles.ini.php (located inlizmap/var/config) the given block :

[jdb:altiProfil]
driver=pgsql
database=name of database
host=localhost (or URL)
user=the login for the database
password=password for the database
search_path=if the table is in a specific schema, otherwise, let "public"

Cas de l'utilisation à partir de l'API IGN

French only 🇫🇷

En raison de l'absence de continuité de service de l'offre Pro IGN, il n'a pas été possible de tester complément l'intégration de l'API. Les tests effectués ont été réalisés sur la base des exemples donnés dans la documentation.

Il est possible que l'intégration ne soit pas optimale, mais cela devrait tout de même être fonctionnel.
