Anomalies, Problems, and Errors Found in LandView^® IV

While performing a Query, you may notice that a "School Enrollment" percent field appears. This field is a duplicate of the "Below Poverty" percent field and is not supposed to exist. Therefore, please ignore this field.

Note to Windows NT/2000 Users
A. Missing TIGER/Line Map- Hardin County, IA
Because of a problem with DVD drivers in Windows NT/2000, it appears as if the folder "\maps\Tiger\IA\19083" on the DVD is empty. This folder contains the Census TIGER/Line^® 1998 layers for Hardin County, Iowa. Consequently, the MARPLOT^® mapping program does not display this map's data. (NOTE: This problem does not affect Windows 95/98 Users).
This problem can be resolved by downloading the file HARDN_IA.EXE. After downloading this file, go to the run menu and select the file and then click OK. This program will present a screen requesting a drive and an folder to extract to. You should specify the drive that you installed the LandView IV software (default is C:) and the folder \LV4 . This program will automatically extract the folder \19083 containing the Hardin County IA map into \LV4.
B. LandView IV Refuses to Run
We have had some reports of people having problems with LandView IV starting on their Windows 2000 machines especially if they are a Dell or DTK machine. It has been reported that when one tries to start the program up the hourglass pauses and then disappears and the program returns to an idle state. We believe this may be due to an incompatibility with the sound card drivers. FileMaker^® is aware of the problem and has come up with some solutions to try and alleviate the situation.

Note to LandView IV Network Users

For those of you using LandView IV on a network you may recall that the file LVMAPS.TXT in the CDMAPS folder, must be modified, as described in the readme.txt (in that same folder) in order for MARPLOT to find the maps on the network. The LVMAPS.TXT has an error in line #41.

It reads:
2 ZIP_CO_2, Zip Code Points

It should read:
2 ZIP_CODE, Zip Code Points

Simply edit the LVMAPS.TXT file, using WordPad or any other text editor, and change that one line. Without this change, MARPLOT will give an error message when it tries to access the Zip Code layer.

Places Missing from the Map

Due to a processing error, MARPLOT place polygons were not created for the following independent cities:
Consequently, any queries performed under the "Place" tab in the 1990 Census containing any of the above five cities will not be shown on the map. When mapping the search collection you may encounter a Marplot Error message stating "One or more of the objects to be shown were not found."

Because these independent cities are treated as county equivalents, you can select the appropriate city under the "Counties" tab and then map it that way.

Population Radius Function Updates
Because of different questionnaire content the population radius function for Puerto Rico does not work properly on the LandView IV DVD. Copying the following file:
MAC: Landview4.sit.hqx
Windows: landview.fmx
to the SYSTEM folder will allow the population radius function to work properly for Puerto Rico. The SYSTEM folder is located under the LV4 folder on the hard drive. You will need the MAC utility Stuffit to unpack this Windows format file on a MAC. After unpacking the result should be the landview.fmx.

LandView IV Demo
There is a processing error with the LV4 Demo for New Castle County, Delaware. Instead of showing 362 block groups like the LandView IV product, the demo only shows 5.
