• County: Statewide
• Community: Statewide
• Basin: Statewide
• Title: Catalog of Vertical Control Benchmarks State of Colorado
• Date: 10/1/1990
• Prepared For: State of Colorado
• Prepared By: CWCB
• Floodplain - Doc Type: Floodplain Report/Masterplan

To gain the most benefits from the catalog, you should use a computer and an electronic copy
of the database to search for a list of reference marks in the vicinity of the site, A copy of the
database may be obtained on diskette from the Colorado Water Conservation Board at the
following address:

Colorado Water Conservation Board
721 Centennial Building
1313 Sherman Street
Denver, Colorado 80203

To use the diskette, you must be familiar with dBase III Plus, or a more recent version and
have access to an IBM-compatible computer which will run the program, Using the dBase
III Plus program and the diskette, you can create a report with a search condition whose
parameters are based on latitude and longitude, For example, suppose a person wanted to
make a list of all reference marks in the vicinity of a point located at 105006'00" longitude
and 38010'00" latitude, By specifYing limits of plus or minus one second of longitude and
latitude, all benchmarks or reference marks in the database within about one mile in all
directions can be listed, An example dBase III Plus search condition statement for this site
is shown below:

REPORT FORM D:CATALOG FOR LONG<=1033500 AND LONG>=1033552 ,AND,
LAT<=401536 .AND, LAT>=401538 TO PRINT

The report will list all the benchmarks in the database within the "blocked area" bounded by
the specified latitude and longitude,
