I have a question regarding converting a vector forest cover layer to a raster layer.
The basis of what I am trying to do is determine what percent of forest cover is within a set of 1x1 km grid cells in arcmap. I originally attempted to do this using fishnet, tabulate area tool, and a vector layer for forest cover, but I got the error message "maximum record length has been exceeded" (if anyone knows a way to get around this without converting the vector layer to a raster, please feel free to also let me know). So, I decided to convert the vector forest cover layer to a raster and try to use the zonal statistics tool. Here, I run into problems where it seems that the numbers do not add up correctly.
First off, I originally merged two vector files for secondary and primary forest into one vector file I called "forest"; using the merge tool; is it possible I executed this wrong and lost important information in this process?
Next, should I be using the feature to raster tool or the polygon to raster tool? I am wondering when I used the feature to raster tool if I am not inputting the correct information to provide the proper data related to the forest cover pixels. For example, what should be in the VALUE field, can I just put FID? Should it be something for specific? Do I need to be specifying a cell size, and should it be 30? (Since the map is resolution is 30x30 m pixels).
