Frequently Asked Questions for Arc/Info Export (.e00) Files
- How do I save an Arc/Info interchange (.e00) data file to my computer?
- An Arc/Info .e00 file is a transferable text file version of the data layer. Download a .e00 file as you would any other text file. (Navigate to the page and use the "Save As" feature of your browser.) Alternatively, Netscape users may hold the Shift Key down as you Mouse Click on any link to initiate a download interface.
The default settings for your preferred web browser (Netscape, Internet Explorer, Opera, etc.) may be set to automatically name all text files with a standard file extension (example: filename.txt). If this is the case, you will need to manually rename any data files that you download back to the original filename.e00 before you attempt to import the data to a GIS Software package. Speak with your Information Technology (IT) support staff for assistance in how to name files on your computer, or how to change the default download settings in your web browser.
ESRI offers ArcExplorer, a free GIS data viewer. The ArcExplorer 2 FAQ page explains how to use .e00 import files with the software and links to the ArcExplorer 1.1 Import Utility.
- How do I configure ArcCatalog to recognize ArcInfo interchange (.e00) files?
- The ESRI software support center provides instructions on how to configure ArcCatalog to recognize .e00 files
- How do I import an ArcInfo interchange (.e00) file into ArcGIS?
- The ESRI software support center provides insturctions on how to import a .e00 file into ArcGIS
- How do I import .e00 files into ArcView and convert the data into shape files?
- The following steps or utilities will help you convert an .e00 interchange file to an ArcInfo coverage. You can then add the data as a theme in ArcView and convert the coverage to a shapefile (Theme -> Convert to Shapefile). Data contained in shapefiles can be edited in ArcView.
- Use the IMPORT7.1 utility that comes with ArcView versions 3.x
(Windows Start Menu -> Programs -> ArcView3.x -> Import71).
- The ESRI Discussion Forum archives a batch conversion script that converts multiple .e00 interchange files into ArcInfo coverages using the ArcView Import71 utility.
- The ESRI Online Support Center reports how to batch Import .e00 files via Avenue.
- The GeoCommunity web site provides data Translation Tools for a variety of specialized data formats, including a set of ArcView Translators.
- How do I reproject .e00 data with the ArcView Projection Utility?
- Read about the ArcView Projection Utility at the ESRI web site. This utility is included with ArcView 3.2 and is available on Microsoft Windows platforms.
- Example 1: How to Change Projections with ArcView (by Curt Abert)
- With the ArcView Project window active, activate the Projector! extension.
(File -> Extensions -> Projector!)
- Define the properties of the View.
(View -> Properties)
- Make the theme you want to project the active theme.
- Click the Projector! button (arrow in black circle, surrounded by 4 dots).
- Click the OK button.
- Define the input projection. Click OK
(use the 'Custom' button if projecting from IDNR Lambert definition... see parameters in table below).
- Define the output projection units. Click OK.
- Define the output projection parameters. Click OK.
- Click 'Yes' to recalculate area, perimeter, and length fields.
- Click 'Yes' to add new shapefile as a theme to the view.
- check the appropriate View you want the new theme added to
- Name the new theme. Click OK.

- Example 2: How to Change Projections with ArcView (an example beginning with data in Lambert Conformal Conic, and concluding with data in Decimal Degrees by Dan Nelson).
- Open ArcView, enable the Projector! extension, create a new View.
- Add a data theme to that view and draw it on-screen.
- Look at the Scale Indicator below the button bars, to the right.
It is blank, because Arc/View doesn't know the linear measurement
units for the data set.
- Under View -> Properties, set Map Units to feet. You are telling
the computer the linear measurement units for the data set.
- Ignore the Projection button in this window.
- Click OK.
- Look at the Scale indicator again. Now a scale value should be
present, because ArcView knows the units are in feet.
- Click the button to start the Projector extension
(arrow in black circle, surrounded by 4 dots).
- You are asked for the input projection, which is the projection of
the data as is stands (ArcView doesn't know this until you tell it).
- A Projection Properties window pops up. It should look familiar, but
don't be confused. It is NOT the same as the one you see under
View -> Properties.
- Click the Custom button. The Lambert Conformal Conic projection we
use is not one of the standard projections offered in ArcView, so we
have to input the custom parameters one by one.
- Under Projection, select Lambert Conformal Conic.
- Under Spheroid, select Clarke 1866 (probably the default).
- Central Meridian = -89.5 (the negative sign is important).
- Reference Latitude = 33
- Standard Parallel 1 = 33
- Standard Parallel 2 = 45
- False Easting = 3000000 (that's 3 million, no commas)
- False Northing = 0
- Click OK
- For Output Units, select decimal degrees and click OK.
- For Recalculate Units?, select either yes or no. It doesn't matter
which you select, because length and area in DD are meaningless.
- Add theme to view? Yes.
- Add it to the appropriate View, presumably View1. Click OK.
- Name the theme. For example: house91_dd.shp. Click OK.
- ArcView now performs the reprojection calculations and adds the theme to
- Now you have two themes in two different projections and coordinate
systems on the same View. This will cause things to be confusing
for the software to display, so you need to get rid of the original
theme and inform ArcView of the new coordinate system.
- Make sure the original theme is the active one, and delete it.
Edit -> Delete Themes -> Yes.
- Open the View -> Properties window and reset the Map Units to
- Click on the "Zoom to extent of all themes button". It's the one
with a symbol of three pieces of paper (evenly spaced) and an arrow,
to the immediate right of the hammer. This re-orients the extent of
the display to the right place in space.
- Draw the new theme on-screen. It should be what you expect to see.
- Add your other theme(s) in decimal degrees and draw them on-screen.
They should overlay properly.
