VT GIS Metadata Standard

12 October 2016
This standard transitions Vermont’s from the FGDC Content Standard for Digital Geospatial Metadata (FGDC CSDGM) standard, which was adopted as the metadata standard for Vermont in 2006, to the North American Profile of ISO (International Standards Organization) 19115:20032 — Geographic Information — Metadata (NAP — Metadata) geographic metadata standard. This ISO Metadata has been adopted as the official standard for all VT GIS metadata in Vermont.

Land Use / Land Cover Codes

25 June 1995
Maps of land use and land cover are fundamental tools for natural resource management and planning. These land use/cover codes provide a standard system by which units of land can be categorized. Land use/cover maps serve to: assess the area and distribution of individual land use/cover categories (such as cropland and pasture, code 21), show the diversity of the landscape, contrast the land diversity of different regions, monitor changes in land use and/or cover over time. The VGIS Land Use/Land Cover Codes have been developed to provide compatibility with existing USGS codes, provide codes tailored to Vermont's landscape, permit land coding at a various resolutions (local, regional and state), avoid and clarify redundant classifications which depend on interpretation.

Map Coordinate System

25 March 1998
Standards for a map coordinate system are critical to retaining the integrity of Vermont Geographic Information System (VGIS) spatial data. Therefore geographic data stored in other coordinate systems require conversion for use in VGIS.

Digital Data Conversion

25 March 2019
The purpose of this document is to provide guidelines covering the digital conversion of existing manually drawn data into GIS format. The goal is to obtain the best possible digital map representing an original analog map. As such, it is assumed that a suitable source map exists. While the ultimate quality of the database is dependent on the quality of the source materials and the care used in automation, the procedures for original mapping are not discussed. It must be remembered that precise automation procedures will not improve an inferior base map.
