Property Data #18

Reassess status of property data with Connor Determine if raster based analysis is feasible Determine if area threshold is necessary

cschloss commented 5 years ago

Hi Connor - what do you think of this approach?

Calculate Acres in GIS to make sure acreage is accurate for the projection we are working in Dissolve multipart all CPAD to a single shape Intersect with parcel data Dissolve output from step 3 on APN Calculate Acres of the output from step 4 Join by attribute the output from step 5 onto the output of step 1 (the parcel data). The join field would be the APN Divide protected acreage (from the joined table) by the total parcel acreage, multiply by 100 Remove parcels with >70% protected (this is where we may need to adjust) does this miss some parcels we should have removed? Would >50% remove some we should have left?)

Hand-off from Connor: N:\Projects\Atlas\data\parcels\round2_analysis\scripts

county_loop_test is the current workspace, county_loop has the full list of county abbreviations that will eventually be added to the final script.

Finish Protected Area Removal

[x] Check all joins by calculating difference
[x] Export table with PARCEL_ID, PA_ACRES, and pa_percent
[x] arcpy join small table to lg_par shapefile attribute
[x] decide on cutoff - explore SD county
[x] export non-pa parcels

Create property rasters

[x] Dissolve non pa parcels on owner
[x] Give unique ID
[x] convert to raster, keep extent identical (in R)

Deal with boundary issues

[x] select parcels within 5m of county boundary
[x] export as shapes
[x] merge to one shape - all counties
[x] dissolve on owner (singlepart - max acreage_
[x] subset to just parcels that changed size by calculating new size and identifying those with larger size than the MAX_acreage)
[ ] covert to raster

Populate property data with

[x] acres within each category
[x] mean, min, max of each SDM
[x] acres of each connectivity category
[x] average HMI
[x] dist to PA
[x] Acres of ICLUS
[x] dist to ICLUS
[ ] dist to DAC
[ ] mean carbon
[ ] acres of 100yr flood
[ ] drinking water watershed
[ ] acres in fmmp cats
[ ] average crop value
