I am a grad student working on a paper and I need a little help.
I am new to GIS, so go easy on me
I am trying to determine how census blocks map into precincts in one county: San Diego.
[For those of you who don't know, census blocks are generally smaller than the precincts, but there is often overlap (one census block might be split by a precinct line).]
I have the shape files for both the precincts and the census blocks (they are free to download at http://www.sangis.org/Download_GIS_Data.htm).
I would like to determine what percentage of each census lies in each precinct. So, basically, I want to overlap the maps and then figure out the areas of intersection (let me know if that does not make sense and I will clarify).
A few questions:
1) Is this possible?
2) I am interested in learning GIS - can I do this by myself or will it be too difficult (I have some programming skills but have never really used GIS...I do have access to arcgis)?
3) If I hired someone to do this, what is a reasonable rate? Does anyone know someone who would be interested?
Thanks for your help!
