South Platte Water Rights Management System

For line and polygon coverages, the binary reference files must be recreated after making
changes. These files are read by SPWRMS to determine the location of elements in the
coverages. SPWRMS does not use a binary reference file to interpret point coverages.

Linear changes After editing a line coverage, the coverage must be built for lines, then the binary refer-
ence file must be recreated. For example:

Arcedit: <perform editing operation on phS_district>
Arc: build phS_district line
System%: createarclu . phS_district

The final step creates the binary reference file "arc.lu" in the coverage's directory. The
createarc.lu executable is located in $SPWRMS/tools/arcinfj.

Polygon coverages After editing the reservoir's coverage. which contains polygon topology, it musr be built
for polygons, and binary reference files must be recreated. For example:

Arcedit: <perform editing operations on ph4_reserv>
Arc: build ph4_reserv poly
System%: createarclu . ph4_reserv
System%: createarcinf ph4_reserv

The two final steps create binary reference files for the line and polygon information in the
coverage. These two files "arc.lu" and "arc.inf', respectively, are read by SPWRMS to
determine the location of elements in the coverage. The creatarclu and createarcinf execut-
abies are located in $SPWRMSltoolslarchinf/.

Point coverages Since SPWRMS does not use a binary reference file to interpret point coverages, the only
necessary step to perform after editing such a coverage is to build for points. For example:

Arcedit: <perform editing operations on phS_recharge>
Arc: build phS_recharge point

After the coverage has been built for points, SPWRMS can interpret the contents of the
edited coverage.

Adding a new structure

To add a new structure to the system, modify the ArclInfo coverage.

Modifying the Arc/Info
coverages

1. Digitize the new point into the coverage; i.e., spatial layer containing structures. The
structure must be located on the stream network.

2. Attribute the point appropriately. Assign a water district and ID to the point so that it
can be uniquely identified within the SPWRMS application.
Arcedit: calc sid# = <structure's state ID number>
Arcedit: calc wd# = <appropriate water district number>

3. Connect the new point to the stream network coverage. The point must be associated
with a node in the stream network (see "Modifying the Stream Network" below).

4. There is no need to update the Informix tables because the structure should already be
present in phS_structures.
