Task: Site Generation

Task Description: Generate Sites for Quad-based States

This document modified on: 4/26/02

Task: Create sites for selected state (not IL).

Rationale: Allow automatic creation of site nodes for the upcoming trapping season based on the allgrids shapefile from the decision meetings and the geographic baselayers.

Timeline: January through March

Brief Process Description:

Gets base sites and any necessary state sites from master sites, creates intensive grid sites, assigns all necessary attribute data.

Merges all sites into one shapefile.

Buffers sites by 30% of the inter-trap distance and creates target circles for each site.
Zips the sites and target circles shapefiles and places them on the ftp site.

Notes: The following scripts are compiled and saved as an extension – site_generation.avx – located at abyss\\utilities\.

Processes:

Sites Generation qdbased

Find and add to View basesites and allgrids for selected state and county and quad shapefiles

Select and convert to a new shapefile all points from the master sites shapefile that intersect the selected state.

Assign gridtype from the allgrids shapefile to the basesites.

Select and convert to a new shapefile basesites that have agreement between gridtype and utm coordinates (evenly divisible by gridtype number)

Select and convert to new shapefile all intensive grids (500m) in the allgrids shapefile.

Add new ID field and assign unique number to each intensive grid

Intersect and convert to new shapefile intensive grid theme with quads theme ( qdcode and zone fields from qds theme)

Sort new grd_qd table by intensive grid ID then qdcode

Add new grid number field to grd_qd table and assign unique values per quad

Select blocks by zone and project selected ig blocks to appropriate utm zone

Generate 500 meter sites for each ig block in each zone

Project 500m sites back to albers8 and merge them together, then delete ig sites that do not intersect the blocks

Identity 500m sites with the ig blocks to Block_id and Grid_id field values

Sort 500m sites table by block-ID, UTMN (descending), then UTME

Assign new site numbers to sites unique to each Block_ID

Identity 500m sites with Allgrids shapefile to get dynamic attributes (Project, traptype, agency, gridtype)

Add and fill state field

Identity 500m sites with quads and counties themes

If state = IN, then add appropriate state 3k sites and assign all required fields (project, traptype, agency, gridtype, quad, county, etc)

Merge basesites, intensive grid sites, and state sites into new shapefile and add it to the view

Remove all intermediate shapefiles from the view, and delete intermediate tables from the project

Notes: If site addition/deletion edits have been made to previous versions of a state’s sites shapefile, these changes will need to be implemented after the site generation routine has been run and before the target circles are created.******
