ESRI ARCGIS 8.2 Data

Most users with ArcGIS 8.2 installed on their computer can access the ArcMAP project files on the CD-ROM.

There is one ArcGIS ArcMAP project on the CD-ROM:
arctic_g.mxd -  the layers are similar to those in the ArcView 3.2 project.
Bathymetric data were excluded from the project because that layer is too large to provide satisfactory performance.
 

This project is supplemented with an ArcReader project file - arctic_g.pmf. ArcReader is free ESRI software that allows users 
without  ArcGIS 8.2 to access this ArcGIS project.
 
 

ESRI ARcInfo Data

There are three subdirectories with ArcInfo data on this CD-ROM:

1. cover_st - all ArcInfo coverages in Polar Stereographic projection
2. cover_g  - ArcInfo coverage in geographic coordinates
3. export - all ArcInfo EXPORT format files in Polar Stereographic projection (.e00 extension)

This digitally compiled map includes geology, oil and gas field centerpoints, and geologic provinces of the Arctic (North Pole area - North of 63⁰ N 
latitude). This digital compilation is an interim product of  the U.S. Geological Survey's World Energy Project (WEP) and part of a series of geologic
maps published on CD-ROM.  This worldwide series of geologic maps was released by the U.S. Geological Survey's World Energy Project during 
1997 - 2002. The goal of the WEP is to assess the undiscovered, technically recoverable oil  and gas resources of the world. Results of this assessment 
were reported in 2000 (see USGS DDS-60). 
For the World Energy assessment, the World was divided into eight energy regions which correspond approximately with the economic regions
of the world as defined by the U.S. Department of State. Each region was divided into geologic provinces.  Province boundaries for the Arctic were 
taken from USGS DDS-60 and projected to Polar Stereographic projection.

The following people, with their responsibilities, were involved in producing this CD-ROM: 

General guidance - Gregory Ulmishek 
Digital Geologic Map Compilation in Arc/Info - Feliks Persits 
Legend design -Feliks Persits and Gregory Ulmishek 
Geologic Attribution - Feliks Persits 
Documentation in the form of FGDC-compliant metadata- Feliks Persits 
Arcview and ArcExplorer projects - Feliks Persits 
Map design and verification - Feliks Persits and Gregory Ulmishek 
CD-ROM implementation - Feliks Persits 

This CD-ROM was compiled according to the methodology developed by the U.S. Geological Survey's World Energy Project .
The geologic map of the Arctic was compiled and synthesized from the Circumpolar Geological Map of the Arctic, by Okulitch A.V., Lopatin B.G., 
and  Jackson H.R., scale 1:6,000,000, published by the Geological Survey of  Canada in 1989 (see References ). Specific details of the data sources
are given in the metadata files on this CD-ROM.  Map units were kept as close as possible to original map (more than 100 unique values).
These Arctic maps were compiled using  Environmental Systems Research Institute Inc. (ESRI) ARC/INFO software. Political boundaries and 
cartographic representations on this map are shown (with permission) from ESRI's ArcWorld 1:3M digital coverage. They have no political
significance and are displayed as general reference only.  Portions of this database covering the coastline, rivers and country boundaries
contain proprietary property of ESRI. (© 1992 and 1996, Environmental Systems Research Institute Inc. All rights reserved.
The bathymetric data were derived from the International Bathymetric Chart of the Arctic Ocean (IBCAO) which was downloaded from the NOAA web site.
Oil and gas centerpoints were derived from Probe 4.0 database - proprietary property of Petroleum Information/Dwights LLC d/b/a/IHS Energy Group.
Specific details of the data sources and map compilation are given in the metadata files on this CD-ROM.

 This map has been compiled from the Circumpolar Geological Map of the Arctic, by Okulitch A.V.,  Lopatin B.G., and  Jackson H.R.,
 published by the Geological Survey of Canada in 1989 at a scale 1:6,000,000.

Data processing steps:
1. The original paper map was scanned on a large format Ideal scanner in gray scale mode with a resolution of 200 dpi and transformed to ArcInfo Grid.
2. The grid from step 1 was transformed to Polar Stereographic projection using a second order polynomial transformation (ArcInfo GRIDWARP
utility).
3. Reference points for transformation were a combination of latitude-longitude intersections taken from the map and the same tics projected to Polar 
Stereographic in ArcInfo using the PROJECT utility. 
4. A number of piecewise rubber sheeting transformations were applied to the grid from step 3 using ArcInfo CONTROLPOINTS and ADJUST
utilities.
5. Reference points for transformations were taken from ESRI's digital shoreline data layer projected to Polar Stereographic projection.
6. On-screen digitization was performed using the rectified grid from step 5 as a backdrop in ArcInfo ARCEDIT.
7. In the geology coverage, geologic attributes were assigned to the AGE and AGE_GEN items of the Polygon Attribute Table (PAT). Onshore and 
offshore polygons were attributed separately.
8. Geologic age attributes of the Canadian portion of this map were compared with those from the Geological Map of Canada CD-ROM (Map
D1860A, 1997). As the first step more than 600 unique values from Map D1860A were  transformed to the corresponding ages of this map legend and 
used as a reference in assigning final age values.
9. The International Bathymetric Chart of the Arctic Ocean (IBCAO) was downloaded from NOAA web site 
http://www.ngdc.noaa.gov/mgg/bathymetry/arctic/arctic.html   in ArcView shape file format, converted to ArcInfo coverage, and clipped with the geology 
coverage.
10. The USGS Geologic Provinces from the USGS DDS-60 publication were projected to Polar Stereographic projection, and clipped with the 
geology coverage.
