II..FAQ:
A..What projection is the data?
Please see the notes above.
B..Can the NAD83 2002 Contour data be used with the rest of the GIS data?
Only if the software being used is capable of re-projecting one or both of the data sets.
C..Can the NAD27 2002 Contour data be used with newly collected GPS points?
Yes - either the software being used is capable of re-projecting one or both of the data sets or the GPS data is downloaded in NAD27 coordinates (please see the GPS unit documentation).

H..How do I use the different sets of data with AutoCAD? III..Suggested usages: A..Users of Arc/INFO & ArcView should request type
A. Note: Depending on intended usage ArcStorm licensing may be required (NOT needed for read-only usage).
B..Users of ArcGIS, ArcView, & third party programs capable of using/importing shapefiles can request type C.
IV..Explanation of Tiling schema: A..Via ArcStorm the database for Medina County is
broken into 66 irregularly sized and rectangularly shaped tiles. The tile
numbering follows a density/extent method, whereby the tile containing the
largest area is 1 and the second largest is 2, with all tiles having an
initial density of 2500± polygons. V..Special notes for each type: A..Standard ArcStorm: 1..The owner INFO Table is addressed as
county@@owner, allowing county as the initial database name. a..Obtainable from ArcView as
<drive_or_mount_point>/county/arcstorm/infotabs/1/info/owner (ie. E:\county\arcstorm\infotabs\1\info\owner
) with File Type set to INFO. 2..The library is county.county, allowing county as
the initial database name which is highly recommended. 3..All arcs follow a ftr_code schema derived from
the `arc layers precedence chart', (included). 4..All lot dimensions are dynamic size in layer
.parcel, annotation subclass lotdim. 5..The parcel layer is .parcel. a..Obtainable from ArcView as Add-Theme with the
Libraries option on. 6..The address layer is .house. a..Obtainable from ArcView as Add-Theme with the
Libraries option on. 7..In addition to the data files there are
configuration files included for use: a..<drive_or_mount_point>/arcview/arcexe70/tables
(ie. E:\arcview\arcexe70\tables) contains the arcstorm database
location information needed for ArcView users. The file <drive_or_mount_point>/arcview/arcexe70/tables/arc0000.dat
(ie. E:\arcview\arcexe70\tables\arc0000.dat) is set to a default value
of E:\county\county. This can be changed if required, but be careful to only
change the drive letter to the drive letter or mount point of the data download.
Once the file is changed you will need to save it to a writable disk in a
subdirectory named tables and make sure the environment variable that follows
points to the directory that contains the tables subdirectory which contains
the new file.
In addition there is an environment variable that must be set: ((1)) For ArcView/PC users you must also `SET
ARCHOME=E:\arcview\arcexe70' in your C:\AUTOEXEC.BAT file or copy
<mount_drive>\arcview\dos_root\esri\av_gis30\arcview\etc\startup to your
arcview installation directory (ie. copy
E:\arcview\dos_root\esri\av_gis30\arcview\etc\startup C:\esri\av_gis30\arcview\etc
). Note: If you have made other changes to your startup file Do NOT copy
the download startup file over yours, please see the ArcView on-line manual for
information on how to set ARCHOME ((2))For ArcView/UNIX users who also have Arc/INFO
you must copy the file from the download and put it in your $ARCHOME/tables
directory (ie. cp /cdrom/cdrom0/arcview/arcexe70/tables/* /opt/arcexe71/tables
). Make sure that $ARCHOME is set in the environment for the shell (
ie. setenv ARCHOME /opt/arcexe71). If not it should be set similar to
/opt/arcexe71, otherwise the ARCHOME environment variable can be set to
<mount_point>/arcview/arcexe70 (ie. setenv ARCHOME /cdrom/cdrom0/arcview/arcexe70
). b..<drive_or_mount_point>/arcview/arcexe70/arcstorm/county
(ie. /cdrom/cdrom0/arcview/arcexe70/arcstorm/county) contains the
arcstorm database location information needed for ArcStorm users. This file
may need customized by the user if the mount point of the database does not
correspond directly to the original configuration used by Medina County or if
the default database number conflicts with an existing database on your system
and must be edited to set the proper node name for your system. The file is
set to a default location of /maps/county with a database number of 3 and no
node name. The file will also need copied to your $ARCHOME/arcstorm directory (
ie. cp /cdrom/cdrom0/arcview/arcexe70/arcstorm/county /opt/arcexe71/arcstorm
). 8..Following is an example of how to setup an
ArcView session to properly view the ArcStorm data for the parcel polygons:
a..Open ArcView. b..Open a new view. c..View -> Add Theme -> E: -> coverage
-> tdn (in left hand window)(pick on folder not name) -> polygon -> OK
d..View -> Add Theme -> Libraries -> county
(double click) -> parcel (in left hand window)(pick on folder not name)
-> polygon -> OK e..View -> Properties -> Area Of Interest
-> Theme -> Tdn -> OK -> OK f..Click on draw box for theme parcel.
B..Shapefiles: 1.. .
VI..Media types available: A..Download Only unless specified.
Packages no longer apply - please see the download site.
Yes - By replacing the jgw/wld files with the ones residing in the nad83 directory/folder.
No.
No.
The links below have been removed from the Autodesk site, please contact Autodesk support or your reseller.
First and foremost this information is based on feedback & the Autodesk website.
The contour data is supplied in DXF format and can be imported via the "DXFIN" command.
The orthophoto data is reported to be usable as a backdrop in versions of AutoCAD post R13 or R14 (it is unclear which) but it is unclear as to whether the geographic location information is used or if the end-user must place each tile manually.
The tax-map data in shapefile format should be usable via the "MAPIMPORT" command supplied with "Map" & "Land Desktop"
