About the data that comes with ArcView
 About this data

ESRI provides an extensive set of data that is ready for you to use in your work. Every data source is fully documented in this on-line help topic. For each data source there is a brief data source description, information on the number and kind of geographic features, and attribute field descriptions. You can display a "snapshot" showing an example for most feature classes. Technical descriptions provide the data source lineage, coordinate system, useful display scales, and so on.

As you create your own projects, add your own themes, look at attribute tables, and so on, you may have questions about the data. You can find additional information about the data in this help system, and you can find by browsing the help that additional data can be found on the ESRI Data & Maps CD-ROMs. The ESRI Data & Maps CD-ROMs have the following directory structure:

Technical description

GeoDataset name:  IRS 5 meter panchromatic. Image

The Sample IRS Image dataset contains a geocoded IRS Panchromatic image of the greater Orlando Florida region.(Note: the data source IRS.tif  is delivered on the ArcView CD-ROM.)

File Names:

IRS.tif -- Indian Remote Sensing Satellite imagery

Path:

ESRI Data & Maps 5 (CD) \images

GeoDataset type:

 IRS.tif  is a geocoded satellite image acquired by the Indian Remote Sensing Satellite in early 1997.  The .tif image is an uncompressed tiff (tagged image file format) with a .tfw file.

Coordinate system:

Florida-East StatePlane (NAD27) in feet.

General description of the IRS image.

IRS panchromatic imagery offers 5.8-meter spatial resolution, is among the highest resolution satellite imagery available on the commercial market today. IRS imagery is a gray-scale  image which providing a unique combination of large-area coverage without compromising spatial detail. The IRS satellite has the ability to revisit the same location every five days.

IRS imagery products are ideal for applications that do not require a high degree of positional accuracy. For many applications, five-meter panchromatic imagery provides the perfect balance of detail with a big-picture overview. Such applications include urban planning, port monitoring and emergency response.

            Example of the level of detail seen on the IRS 5.8 meter Imagery

Useful display scales:

Largest scale:  1:26,000

Smallest scale:  1:70,000

Usage notes:

When overlaying vector data on the image the view must be projected into Florida-East  State Plane (NAD27) in feet before you add the Orlando Image data source to the view. This step is necessary because the vector data sources are in latitude and longitude coordinates.

General description of the Landsat TM image.

Landsat  imagery is acquired by the U.S. Landsat Thematic Mapper (TM) sensor. This imagery has 30-meter spatial resolution, is resampled to a 28-meter pixel size, and covers a 31,000 square-kilometer scene size. The Landsat TM Sensor acquires its data from an altitude of 705Km . The TM sensor acquires seven bands of multispectral information in the visible, near-infrared, short-wave shortwave infrared and thermal infrared portions of the electromagnetic spectrum.  The scene below was created by combinding the visible bands into a natural color composite which was georeferenced to the USGS 1:24,000 Topo maps.

[nn] represents the standard postal abbreviation for the state. This data was extracted from the standard Geographic Data Technology line water layer and includes only Fcc codes H10 and H11.  These line segments were chained and thinned to serve as a reference cartographic layer.  Many of the cartographic problems with this data inherent in the original 1:100,000 source data remain, however for small areas they make a nice cartographic addition to many base maps.

U.S. States and Counties - Technical Description

GeoDataset names:  States/Dtl_st and Counties/Dtl_cnty

Shapefile names:  States.shp, Dtl_st.shp, Counties.shp and Dtl_cnty.shp

Path: ESRI Data & Maps 1 (CD) \usa,  ESRI Data & Maps 2 (CD) \usa,  ESRI Data & Maps 1 (CD) \usa,  ESRI Data & Maps 2 (CD) \usa

GeoDataset type: States and Counties are ESRI shapefiles with associated attribute tables.

GeoDataset lineage: U.S. States and Counties were generalized from ESRI's ArcUSA 1:25,000,000-scale database. The U.S. subregions are as defined by the U.S. Bureau of the Census, except that in this GeoDataset New England is classified as a subregion instead of a region.  Detailed states and counties were created by aggregating 1990 Census tract geography to county and then to state areas.  The boundaries are therefore consistent with the boundaries of the Census tracts and have all of the detailed vertices necessary to maintain consistency with the tract level of detail.

The demographic attributes in this table come from Summary Tape File-1A (STF-1A) data published by the U.S. Bureau of the Census based on the 1990 Census of Population. The farm attributes come from data published by the U.S. Bureau of the Census based on the 1987 Census of Agriculture.

Coordinate system: Latitude/longitude in decimal degrees

Datum Name: Dtl_st.shp, Dtl_cnty.shp, States.shp, and Counties.shp are in North American Datum of 1983 (Hawaii is in Old Hawaiian Datum).

Coordinate precision: Double.

                  Data Quality Information

Attribute Accuracy

  Attribute Accuracy Report:  The partial attribute list identifying 14 railroad ownership and trackage rights are based on information received from the FRA.  A partial quality control evaluation of the accuracy of these attributes was performed on the database.  The likelihood of attribute errors is greater in the urban than in the rural areas.  The railroad ownership and trackage rights attributes are not complete.  Of the 174,428 line segments in the data set only 61,183 (approximately 35 percent) contain a value for the first railroad owner.  Of 174,428 line segments, only 23,896 (less than 14 percent) contain a value for the first trackage right.   For each ASCII attribute file a corresponding dBase format attribute file is supplied.  Due to the requirement for the file name extension 'dbf', the attribute file number is  included in the file name prefix (RAIL100K.TL2 contains the same attributes RAIL1TL2.DBF).

  Logical Consistency Report:  The database is interconnected and is a flowable network.  However, there probably are occasions where the connection between links are not exactly in the correct geographical location.  There should be no redundancy of lines or nodes in the database.  Initial QC checks found no obvious under- or overshoots. The database, however, is geographically accurate, at the 1:100,000 scale

  Completeness Report:  The only attribute data included in this initial version of the 1:100,000 scale network are track ownership and trackage rights (for 14 railroads) and the State FIPS Code for the links.  There are no attributes listed for Sidings.  The ownership/trackage attributes were generated by conflating the FRA's 1:2,000,000 and the 1:100,000 TIGER/Line databases to the enhanced 1:100,000 DLG database. The railroad ownership and trackage rights attributes are not complete.  Of the 174,428 line segments in the data set only 61,183 (approximately 35 percent) contain a value for the first railroad owner.  Of 174,428 line segments, only 23,896 (less than 14 percent) contain a value for the first trackage right.

      This version of the data set contains no node attributes.

      The sequence number (SEQ) in the ownership (RAIL100K.TL1, RAIL1TL1.DBF) and trackage rights (RAIL100K.TL2, RAIL1TL2.DBF) attribute files may not truly reflect the number of railroads having ownership or trackage rights. In some cases the data provider skipped sequence number(s).  For example, LINKID = 2010 has only a single Trackage Right assigned at SEQ eight.

  Ending Date of Information Content:  1996

  Thematic Quality:

    Thematic Accuracy Report::  The accuracy of the fields MILES, KM, FCLASS, SIGN1, NHS, and STRAHNET from the description section of the link table is consistent with State supplied information for the years 1992 and 1993. All other attributes in the description of the link table are unverified.

  Logical Consistency Report:  All node and link topological relationships and uniqueness of entity Ids are verified by computer algorithm.

  Completeness Report:  The complete urban principal arterial system and arterials in rural areas as reported to FHWA by December 1992 are inventoried in the database.  Functional classes below arterial vary on a State by State basis.

  Positional Quality:

    Horizontal Positional Quality:

      Horizontal Positional Accuracy Report:  The elements of the NHPN have been conflated to the 1:100,000 DLG-3 data set which maintains a nominal accuracy of at least 80 meters. Where new roads have been added which are not in the DLG-3 database link alignments have been digitized or converted from digital sources acquired from State DOTs with a map scale of at least 1:100,000.

          Enumerated Domain:

            Enumerated_Domain_Value:

                           0 - Not a boundary node                           1 - County Boundary                           2 - Adjusted Urbanized Area                           4 - Adjusted Small Urban Area                          10 - State Border

     Note: The values for BNDRY are additive and can be used to describe a node which lies on the border of more than one boundary. For example a node at a State border will also be a county border node and will therefore, have a value of 1 + 10 = 11.  Similarly a node which lies on the boundary of an Urbanized Area and a small urban area will have a BNDRY value of 4 + 2 = 6. If it were also a county boundary it would have a value of 1 + 2 + 4 = 7.

Useful display scales

The statements on useful display scale are rough guidelines for the largest (zoomed in) and smallest (zoomed out) scales at which data sources are most useful. The factors that most affect useful display scale are level of cartographic generalization, feature density, and positional accuracy of the data. Other factors, such as background color, symbol shape and size, combination with other themes, window size, and monitor resolution all influence the scale range.

The useful display scales we suggest are based on viewing the data under the following conditions:

1. A 13-inch color RGB monitor with 640 x 480 pixels

2. A view window size of 4.5 inches high by 6 inches wide

3. All of the features in the data source are displayed

4. The maximum scale value for point data was determined by displaying line or area data for features closely associated with the point data. For example, Average Daily Traffic Volume Points were displayed with highways.

5. The following map projections were used:

For world data sources

World:  Robinson

Polar:  Lambert Azimuthal equal area

For North America data sources

Albers Equal-Area (North America)

World Gazetteer

Technical description

GeoDataset name: Gazetteer

World Gazetteer contains proper names for map features around the world. The gazetteer includes attribute and annotation name information from various layers of the Digital Chart of the World.  The original source of the names is the United States Defense Mapping Agency (DMA) - now called National Imagery and Mapping Agency (NIMA) - Operational Navigation Charts(ONC) at 1:1,000,000 scale.  This layer may be used to find locations by their proper name anywhere around the world.

  Gazetteer -- World Gazetteer

156,638 points, 2 descriptive fields. Describes proper names for map features.

Fields:

Text -- The name. Spellings are based on Names as they appeared on the ONC. (String)

Type -- This item contains the type of feature to which the name pertains.  A legend file is included with this data which has the following values:  administrative name, airport, country name, cultural landmark, desert name, drainage feature, island name, land place name, mountain name, ocean name, and populated place. (String)


World Gazetteer - Technical Description

GeoDataset name: Gazetteer

Shapefile name: Gaz.shp

Path: ESRI Data & Maps 1 (CD) \world

GeoDataset type: Gazetteer is an ESRI shapefile with point features.

GeoDataset lineage: World Gazetteer was developed to support the Place Name Index query for the Digital Chart of the World.  These proper names derived from annotation do not correspond with the true location of the feature because the latitude and longitude coordinate values were derived from the annotation location rather than the map feature itself.  For example, the location for the text identifying the island Sicily was in the Mediterranean sea on the ONC source material.  Locations taken from annotation are based on the lower left corner of the first letter.  Also, the names associated with fuzzy polygons may occur anywhere in the general area of the feature.  For example, the name ‘Rocky Mountains’ is a point located somewhere in the general area covered by the term Rocky Mountains.  Fuzzy polygon names which appeared on more than one ONC sheet will occur more than once.

Coordinate system: Latitude/Longitude in decimal degrees.

Datum Name: World Geodetic System of 1984 datum.

Coordinate precision: Double.

Useful display scales:

Suggested display scales are as follows:

For the entire world:  1:200,000,000

For individual continents:  1:100,000,000

For regions of the world:  1:50,000,000

The density of gazetteer points is important in determining the largest and smallest useful display scales.
