What does this data set describe?

Title:

lakes.shp

Lakes of the Former Soviet Union

Abstract:

This shapefile contains arcs, polygons and polygon labels that describe lakes in the countries comprising the Former Soviet Union. (Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikstan, Turkmenistan, Ukraine and Uzbekistan.) This spatial dataset is available as an ArcView shapefile.

6. How does the data set represent geographic features?
 
1. How are geographic features stored in the data set?


 This is a Vector data set. It contains the following vector data types (SDTS terminology):

• GT-polygon composed of chains (2000)
2. What coordinate system is used to represent geographic features?


 Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 1 degree. Longitudes are given to the nearest 1 degree. Latitude and longitude values are specified in Decimal degrees.

The horizontal datum used is Pulkovo Datum 1942.
The ellipsoid used is Krasovsky.
The semi-major axis of the ellipsoid used is 6378245.
The flattening of the ellipsoid used is 1/298.3.

Why was the data set created?

This spatial dataset is intended to delineate lakes in the Former Soviet Union as a locational reference in U.S.G.S. Open File Report 01-104, "Coal Quality and Resources of the Former Soviet Union - An ArcView Project".

How was the data set created?

1. Where did the data come from?

 

TM (source 1 of 1)

(Ed.), A.V. Tyzhnov , and (Ed.), I.I. Molchanov , 19760000, Obzornaya karta ugol'nykh basseinov i mestorozhdeniy SSR (s ukazaniyem ikh marochnogo sostova) - Survey Map of Coal Basins and Deposits of the U.S.S.R. (with indication of coal mark composition): Ministry of Geology of the U.S.S.R. and Ministry of Coal Industry of the U.S.S.R., Moscow, Russia.

Other_Citation_Details: Published in Russian

Type_of_Source_Media: Paper

Source_Scale_Denominator: 7500000

Source_Contribution: Location and extent of lakes

2. What changes have been made?

 

Date: 2000 (change 1 of 3)

Paper source maps were scanned. Image was vectorized. Map sheets were map-joined. Polygon topology was built. Polygons were attributed.

Date: Jan-2001 (change 2 of 3)

Coverage was projected to Geographic degrees of latitude and longitude coordinates.

Date: Jan-2001 (change 3 of 3)

Arc/Info coverage was converted to ArcView shapefile.

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

 N/A
 

2. How accurate are the geographic locations?

 Dependent on source materials.
 

3. How accurate are the heights or depths?

 N/A
 

4. Where are the gaps in the data? What is missing?

 N/A
 

5. How consistent are the relationships among the observations, including topology?

 Polygon topology exists. Each polygon has one unique label point with unique id, there are no dangles. The coverage is topologically cleaned and built in Arc/Info 7.1.2.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: None

Use_Constraints: None
