High-resolution ecogeographical variable dataset describing Latvia, 2024

Description:This dataset contains 538 ecogeographical variables as raster grids with 100 m cell size. Every layer matches template raster grids (CRS, pixel locations, extent, pixels with values), they cover the whole terrestrial territory of Latvia and are consistent with each other. Files: "HiQBioDiv_EGVs_2024.csv" names ecogeographical variable layers in "HiQBioDiv_EGVlayers_2024.zip"; "HiQBioDiv_EGVs_2024_README.csv" explains fields in "HiQBioDiv_EGVs_2024.csv"; "HiQBioDiv_EGVs_FlowChart_2024.png" visualises relationships between ecogeographical variables in "HiQBioDiv_EGVlayers_2024.zip"; "HiQBioDiv_EGVlayers_2024.zip" contains geoTiff layers with ecogeographical variables. EGV layer's naming convention: {part1}_{part2}_{part3}.tif part1 is a name of the group of variables; part2 is an abbreviated name of the specific variable; part3 is a categorised spatial resolution: "cell" - information from within the cell only; "r500" - a summary of information from an area with 500 m radius around the cell's centre; "r1250" - a summary of information from an area with 1250 m radius around the cell's centre; "r3000" - a summary of information from an area with 3000 m radius around the cell's centre; "r10000" - a summary of information from an area with 10000 m radius around the cell's centre. File format:The layers are gridded geoTiff files and can be loaded in any conventional geographical information system (GIS) or analytical programming languages (e.g. R or Python). Geographic projection:We use the LKS-92 / Latvia TM by default for all layers in HiQBioDiv. Sourcecode:Detailed description of geodata used and workflows in production of every layer is available in an online document. Related work is available at the project's GitHub repository.
