The LandView 6 National DVD Kit contains all the datasets and maps for the 50 States, the District of Columbia and Puerto Rico. This version of LandView is designed for users who have sufficient capacity to contain the necessary data and map files either on a Local Area Network (LAN) or on a local drive. For the National dataset, this is in the order of 12 GB. While the National DVDs contain the MARPLOT® map files specific to the LandView data files, they do not contain the TIGER/Line® map layers--those files providing topological data such as roads, rivers, railroads, etc. These files must be copied from the LandView East and West DVDs which are a part of the kit. Ordering information.
LandView 6 East and West on DVD is designed primarily for users intending to access the LandView data and map sets from a DVD drive on a workstation or laptop. LandView East contains complete data and map sets for all States east of the Mississippi while LandView West contains similar data for all States west of the Mississippi. The States of Minnesota, Iowa, Missouri, Arkansas and Louisiana are common to both DVDs.
While the primary concern of this Help file is the National LandView release, it is well to point out that either release of LandView 6 can be installed to a workstation or LAN. The selection criterion being whether the data on either the LandView East or the LandView West DVD is sufficient to a users needs or whether access to the entire national dataset is required. A LandView Help file, Network Installation of LandView, provides instructions for installation of either format on LAN servers. A LandView Help file, Alternate LandView Installations, provides instructions for installing the formats on a work station or laptop. There are occaisional users who are more restricted in their placement of files. To meet their needs, a Help article has been created in Unique Solutions, as Notes on LandView Installation Procedures.
The LandView application files should be installed on one or more workstations. By default installation is to the root of the C:\ drive, at c:\lv6a. If there are multiple users, a means should be provided for placing the application program on additional workstations. One method is to have the LandView Installation directory available at the same location as the data files. On startup of a newly installed LandView, LandView will automatically access properly installed data and map sets. Disk 1 of the National release contains the Install directory. Sub-directories identify a Windows installation and a Macintosh installation. Only the "install" appropriate to the LAN need be retained. The executable may be moved to the higher level in the Install folder, and it can be renamed as, for example, Install LandView.exe
An LV6 directory that contains LandView data files should be copied to a drive location accessible to the LandView . The LandView application is directed to find an LV6 directory containing a LandView dataset at the root of an available drive. For the National release, because of size constraints, the LV6 directory is split between the two DVDs. Disk 1 contains an LV6 directory with the largest single file in the dataset, blocks.lv6. The LV6 directory on Disk 2 contains the remaining data files. These need to be copied to the LV6 directory copied from Disk 1 to complete the installation.
A Maps directory should be copied to a location so that its contents exactly match file identities and path statements as specified in a marplot.vnx file. As contained on Disk 1 of the National release, the Maps directory has four agency mapsets-Census, EPA and two USGS mapsets, one linked to the GNIS data in LandView and a second for Federal Lands. What is not included and what is required for proper LandView usage is a directory entitled TIGER1. TIGER contains the topological mapsets for all counties (or county equivalents) appropriate to the LandView geography. To complete the installation of the National release, TIGER/Line files need to be copied from mapsets available from the 2-DVD East/West versions of either LandView 5 or landView 6.
An appropriately edited marplot.vnx file needs to be placed at the root level of an available drive. As contained on Disk 1, the VNX file for the National release is generically set to a volume label, LV6. This needs to be replaced by an appropriate drive letter that will complete the path statements. For example, if Maps directory is placed at the root of the R:\ drive, the marplot.vnx file should also reside there, and "LV6", its first line of text, changed to read "R:". Do not write this as "R:\", as the backslash is already contained in each of the subsequent path statements.
As stated above, each of the 2-DVD (East/West) releases of LandView 5 and LandView 6 contains all data necessary to LandView including the TIGER/Line files appropriate to its geography. On each CD is a Maps directory containing a TIGER directory. Nested in TIGER are state directories identified by their postal abbreviations. Nested in each state directory are its county directories identified by FIPS code ( a 5-diget numerical identifier). However, these do not concern us at the moment. Common to both TIGER directories are five states-Minnesota, Iowa, Missouri, Arkansas and Louisiana.
To complete a proper installation of The LandView 6 National DVD, a complete set of TIGER files need to be copied to the Maps directory installed above. From either LandView East or LandView West, the entire TIGER directory can be copied to the Maps directory. On the second DVD, the TIGER directory needs to be opened and the remaining map files copied to complete the set.
A simple method is as follows: With TIGER opened, use Edit/Select All to place the entire contents of the directory in Select mode. By holding down, the [Control] key, de-select the five common state files (MN, IA, MO, AK and LA). Right-mouse click in the highlighted blue area, and Copy. Go to the previously installed TIGER directory and again right-mouse click to Paste. This completes the installation. In Marplot, using List/Map List . . . , you should be be able to identify both agency mapsets and county map files from across the country.
