Introduction
This post covers how to import the soil moisture / Depth To Water layer available via Skogsstyrelsen FTP site. If you followed the steps in the previous post on SLU/Skogsstyrelsen soil moisture you should have the tiles of the Depth To Water layer downloaded on your local machine.
Prerequisites
To follow the processing in this post you must have installed Karttur’s GeoImagine Framework and downloaded the Depth To Water tile dataset as described in the previous post.
Processes
To get the Depth To Water dataset prepared for Karttur’s GeoImagine Framework the following steps are required:
Bounding boxes for tiled datasets
For datasets delivered as tiles, like the Depth To Water dataset, the Framework process BBoxTiledRawData can be used for retrieving the boundary polygons of the tiles. The output of the process is a vector file. The process does not interact with the Framework database but is merely an opportunity for visually inspecting raw data prior to further processing.
Framework process: BBoxTiledRawData
Json command file: 0122_BBoxTiledRawData_slu-dtw
## Create vector bounding boxes for the depth to groundwater (dtw) tiles ##
0122_BBoxTiledRawData_slu-dtw.json
Mosaic the raw tiles
Because the Depth To Water dataset is delivered as tiles, you need to create a virtual mosaic prior to importing and registering it for the Framework database.
Framework process: MosaicAncillary
Json command file: 0125_MosaicAncillary_slu-dtw.json
## Mosaic depth to water tiles ##
0125_MosaicAncillary_slu-dtw.json
The mosaic will just be used as an intermediate layer for creating the SWEREF tiles to be used for the actual processing later. The next step is thus to import the virtual mosaic into the Framework.
Import and register
The layer with Depth To Water is imported and registered (organized) by using the virtual mosaic created in the previous section. In essence this equals importing a single, virtual layer rather than the original tiles.
Framework process: OrganizeProjSysData
Json command file: 0160_Organizeprojsys_slu-diken.json
## Organise depth to water ##
0160_Organizeprojsys_slu-dtw.json
Tile to SWEREF99 system
The virtual mosaic of Depth To Water is represented as an ancillary composition and layer in the Framework database. but we want to use it within the projection system SWEREF (that we created in the post Default region Sweden). In the jargon of Karttur´s GeoImagine Framework we want to tile to a project system region (TileProjSysRegion).
Framework process: TileProjSysRegion
Json command file: 0180_TileProjSysRegion_slu-dtw.json
## tile depth to water ##
0180_TileProjSysRegion_slu-dtw.json
The data is now ready for further processing in Karttur’s GeoImagine Framework.
