Habitat quality model: input raster resolutions

Software Support
1

Hello everyone,

I am using the habitat quality model for my research and I am wondering if the land cover raster has to be same resolution.
I am looking at the years 1994 and 2024, however the two satellite images I have are 30m and 10m respectively. Can I use both or I have to resample to same resolution

Hi Favour,

Thanks for reaching out! As part of the model run, all of the input rasters will be aligned and resized to match the “Current Land Cover” raster’s pixel size, bounding box, and projection. So, assuming you’re planning to use both rasters in a single model run (e.g. using one as the “Current Land Cover” and another as the “Future Land Cover”), this will happen automatically and you shouldn’t need to manually resample your input rasters.

Let us know if you have any other questions or run into any issues!

Thank you Megan. I was able to run my analysis for my preliminary analysis. However because it was a preliminary study I used samples values for my threat and sensitivity table. I am now preparing to run the analysis for my actual project, but I am wondering how to get the appropriate values to do my analysis. I have read that I can estimate those values from previous studies. How reliable is that and do the natural capital project have a standardized values for the tables?

Hi Favour,

I don’t believe NatCap has standardized values for threat rasters or the sensitivity table; the values for each will likely be dependent upon your target study area and species. Threat layers can be sourced from any spatial data that you have that are relevant to your species. Some examples may include: roads sourced from Open Street Map; agriculture or urban areas extracted from your land use / land cover map.

I don’t know of specific sources for sensitivity data, but we do generally recommend referencing past studies and expert opinion. The Publications page on our website includes links to databases of publications that use InVEST models; you could try searching for studies that used the Habitat Quality model to see if any may be helpful or relevant to your project.
