Abstract:
This dataset is comprised of two ARC/INFO coverages, MTRIVERP and MTRIVERA, intended for use in tandem. They represent major river and large river areas in Montana and vicinity, and were built for use in predicting vertebrate species distributions for Montana Gap Analysis (MT-GAP). MTRIVERP contains polygon features; MTRIVERA, arc features.

Both coverages were created from an ARC/INFO hydrography coverage called MTHYGAP (created/edited from USGS 100k DLGs). MTRIVERP was created by selecting out double-line features, as well as islands, and building polygon topology. Attributes then were added to code for presence of islands within major river areas. MTRIVERA was built by manually selecting arcs from MTHYGAP to supplement the double-line features of MTRIVERP, which underrepresented the state's major waterways. This process was necessarily somewhat subjective in nature because stream order or other objective criteria for selecting features were not available in the source digital data.

MTRIVERP and MTRIVERA were never used directly in predicting vertebrate species distributions; rather, they were primary inputs used to create a number of grids that were actually used in the raster-based modeling process (see final Process_Step).

The following metadata elements are required by GAP, but do not parse using the FGDC ms parser (although similar elements can be found later in this document for several of these). For the convenience of GAP users, these elements are listed here. Data Set Identity: MTRIVERP, MTRIVERA; Raster File Format: NA; Raster File Sensor: NA; Vector File Format: ARCE7; Nonspatial File Format: NA; Source Distance Resolution: Unknown; Raster File Number of Bytes per Pixel: NA; Native Data Structure: Vector.

Purpose:
These coverages were produced to create an accurate representation of 100k major river features for Montana. They were built for use in wildlife-habitat relationship modeling of terrestrial vertebrates for MT-GAP.

Attribute_Accuracy:
Attribute_Accuracy_Report: Attribute accuracy assessment not available.
Logical_Consistency_Report:
All major rivers (double-line features) were checked for arc code consistency and polygon closure. Attributes were added to indicate presence of river islands. A total of 3253 polygons were evaluated.
Completeness_Report:
Dataset from which these coverages are derived is complete based on evaluation and editing of USGS 100k DLGs with regard to corresponding published maps (for more information, see metadata for MTHYGAP, cited in Source_Information below, as well as the following USGS webpage: http://rmmcweb.cr.usgs.gov/public/nmpstds/dlgstds.html). Users must determine whether data at 1:100,000 scale are suitable for their purposes. MTRIVERA coverage, as noted above, is by necessity somewhat subjective and was built specifically for MT-GAP vertebrate modeling.

Source_Contribution:
Book that provided map source to guide subjective manual selection of "large" rivers from MTHYGAP so that these could be appended to "major" rivers (double-line features) for complete major/large river coverage for Montana.
Process_Step:
Process_Description:
Select "major" river arcs from MTHYGAP, the double-line features. In ARCEDIT, select MAJOR3 = 600 and MINOR3 ne 666. (Codes in MAJOR3 and MINOR3 were evaluated and simplified for use in MT-GAP; see MTHYGAP.TXT for details. Arcs selected above typically include those where MINOR1 = 200, 605, 606 - shoreline, right, or left bank of major river as defined in USGS 100k DLGs.) PUT selected arcs into separate coverage, RIVER_POLY. ADDITEM "TYPE" and calculate TYPE = 888. CLEAN the coverage to build polygon topology (fuzzy tolerance .005).

Process_Step:
Process_Description:
Select islands from MTHYGAP: in ARCEDIT, select MAJOR3 = 200. PUT to a separate coverage. ADDITEM "TYPE" and calculate TYPE = 999. BUILD polygon topology. Note that all islands are selected here, whether they fall in rivers or in lakes; it was not possible to reliably separate islands by type. Only those islands falling within rivers, however, are counted toward item ISLAND (see below) and included in the final polygon coverage.
Source_Used_Citation_Abbreviation: MTHYGAP
Process_Date: 1998
Source_Produced_Citation_Abbreviation: ISLANDS
Process_Step:
Process_Description:
Identify river segments (polygons) containing islands. In ARC, use UPDATE command to append ISLANDS coverage to RIVER_POLY, creating MTRIVERP. ADDITEM "ISLAND" to MTRIVERP coverage. In ARCPLOT: reselect riverisland poly type = 999; aselect riverisland poly adjacent; calculate riverisland poly island = 1; clearselect; reselect riverisland poly type = 999 and island = 1; calculate riverisland poly island = 0; clearselect. Delete extra islands using the same sort of logic. At this point, the major river coverage, coded for segments with and without islands, is ready for use in MT-GAP analyses.

Source_Produced_Citation_Abbreviation: MTRIVERP
Process_Step:
Process_Description:
Supplement the selected "major" rivers, which underrepresent the state's major waterways. From MTHYGAP, select MAJOR3 = 600 and MINOR3 = 666. (Arcs assigned MINOR3 = 666 were selected using Montana Gazetteer as visual guide and, in ARCEDIT, manually selecting large river arcs (not including the double-line features above) from MTHYGAP). PUT into separate coverage, MTRIVERA. ADDITEM "TYPE" and calculate TYPE = 777. This separate coverage is not appended to final MTRIVERP coverage because one contains arcs and the other polygons; however, MTRIVERA is used in conjunction with MTRIVERP to create grids of large rivers for MT-GAP analyses.
Process_Date: 1998
Source_Produced_Citation_Abbreviation: MTRIVERA
Process_Step:
Process_Description:
Here, we provide information on how the MTRIVERP and MTRIVERA coverages were used to produce intermediate/temporary 90 m grids for use in vertebrate modeling for MT-GAP. The generic logic is as follows:

STEP 1. Identify the desired features: major rivers (those in MTRIVERP), large rivers (those in MTRIVERA), both, major rivers containing islands (polygons in MTRIVERP where TYPE = 888 and ISLAND = 1). If needed, create a vector layer of the desired features using the RESELECT command in ARC to extract the desired set from MTRIVERP into its own coverage. To produce some intermediate grids, the BUFFER command then was used to identify distances to the selected features. For example, "buffer river_arc rivarc1km # # 1000 # line # full" would buffer large rivers by 1000 m.

STEP 2. Enter the GRID module. Setmask and setwindow to ensure that the output grids are "snapped" to the state boundary grid with pixel increment, rows, and columns matching all other vertebrate modeling inputs. Specifically, the commands "setmask stategrid; setwindow stategrid mtgapveg" were used.

STEP 3. Use a CON(POLYGRID()) or CON(LINEGRID()) statement, then a CON(ISNULL) statement, to create the desired output grid (which, for modeling purposes, must contain values of 1 and 0, without any NODATA). For example, the commands "majrivtemp = con((polygrid(riverisland, type, #, #, 90)) == 888, 1, 0)" and "majrivgrid = con(isnull(majrivtemp), 0, majrivtemp)" would create a 90 m grid of major rivers where all cells within the state are coded 1 or 0. If a grid of both major and large rivers were desired, the user would next need to create a corresponding 90 m grid of large rivers: "lgrivtemp = con((linegrid(river_arc, type, #, #, 90)) == 777, 1, 0)" and "lgrivgrid = con(isnull(lgrivtemp), 0, lgrivtemp)". The two grids could then be merged into one: "rivertemp = merge(con(majrivgrid == 1, 1), con(lgrivgrid == 1, 1))" and "rivers = con(isnull(rivertemp),0, rivertemp)". (GRID users will notice that some of these steps could have been skipped, but because we wanted major rivers and large rivers in separate grids as well as a combined one, it was easiest to always use the CON(ISNULL) statement, although it made subsequent MERGE functions more complicated.)

Numerous grids were created following this sequence.
