Hello @swolny ,
Thank you for your indepth review on the case I am dealing with, it is very much appreciated!
I will use the “hdr.adf” file to input for the current land cover layer instead of the “.ovr” file. It was not specified in 4.1.4 data needs of the current user guide therefore I chose the largest file as I assumed it would have the data it needs to run the model. I will make a note of this and use TIFFs instead of a GRID in the next model run after I work on the following tasks below.
I am not sure why there is a value of “-32768” either as it is not a value I have marked anywhere in the process of creating these layers and tables. I have also put in the entry for this number in the sensitivity table to run the model when I got this error and then bypassed it to the bounding box error at one point with some older data in the project I am working on from previous years and it was able to run successfully.
I have used your advice and now I was able to run the model to completion as well. I see the odd output habitat quality values as well though I have no idea why the habitat quality values are either very low or 0/1. Shall I edit the NoData values within the lake_c threat raster on it’s attributes table? I see that note in the user guide as well, I apologize for that mistake and will change the values to 0.
For the future threat rasters, I exported the current threat rasters with 16bit unsigned which may have been the problem at it has a greater range of values that each cell can contain. I will export those using a lower range of values like unsigned 8 bit. I will re-export the future threat rasters and change the no data values in the lake_c threat raster and review the outputs to understand better these problems we are facing.
Thank you for directing this issue to @jdouglass I look forward to hearing your input about the 0/1 habitat quality outputs, missing coordinate systems, and low degradation values. I really appreciate the effort you have shared to help me with these issues @swolny , I will work on them and correct my methedoogy befor eI use the data in the model.
I will be heading out of my office in an hour and be back tomorrow around 7am CT and respond to any replies promptly! Thank you everyone!
I have started exploring the output habitat quality raster and I can see some values in between 0 and 1 however there is no attributes table or frequency table where I can view everything that is showing on the raster unless I zoom into areas. When I try to change the symbology to unique values it does not work as it states that the number of unique values I have in the data is greater than the set limit of 65536. I’m not sure if I should change the maximum number of unique values.
I can see degradation layer has very low values as well though I am not able to view a table for it either. Neither of these output layers have a coordinate system attached to it as is on a compleltly differnt area than the rest of my layers.
I will change the bit depth of the threat layers and rerun the model and try to change the no data values of the lake_c threat raster tomorrow morning and report back as soon as possible.
I quickly wanted to add that a lot my layers that I used to create the threat rasters and land cover layers are all swked. None of them have projections coordinate systems suddenly after I ran the model. They all had WGS 1984 Web Mercator Auxiliary Sphere, however they do not now and they are not on the country they originally were. My basemap has also turned horizontal…I’m not sure what happened though before during my failed model attempts my csv files kept getting combined into one field from multiple fields.
I am not sure if the InVEST 3.6 model is reworking some of my data, shall I download older InVEST versions? I will work on fixing all of these layers.
