Title: Costilla State Survey

Description:

Abstract: Townships, ranges, and sections of Costilla County from the so-called Costilla State Survey.

Purpose: To provide some general reference system for Costilla County based on township, range and sections.

Supplemental_Information: This township, range and sectionalized version of Costilla County is not part of the public land survey system (PLSS). However, in 1914, Albright and Martin conducted a sectionalized survey for Costilla County and this survey is referred to as the AMS survey. This survey has been updated through local surveying and there are many discrepencies between current surveys and the original AMS survey. This representaion is a combination of local survey records and the AMS survey.

Process_Step:

Process_Description: The original cloth map of the AMS survaey and mylar assessor's maps were scanned and digitized using AutoCAD Map 3.0 and TrueInfo scanning software. The digitized layers were georeferenced to adjacent PLSS coverages from the BLM GCDB using ArcInfo 7.2 and corrected to the orthogonal .
