Surface Ownership

These seven layers were derived from ALP: Administrative Boundary Proclaimed Boundary District Boundary Surface Ownership Sections Townships Wilderness Data for six of the seven feature classes was loaded from individual ALP coverages for each Forest using ArcCatalog. The ALP coverages for the forests break on township lines rather then forest boundaries. Although the ALP coverages were edged matched some additional edge matching was required. Topology rules were created for editing utilizing "Must not Overlap" and "Must not have gaps" rules. Forest Administrative Boundaries were created by dissolving the Ranger District Boundaries. Notes: 1. Forest Administrative Boundaries were created by dissolving the Ranger District Boundaries. 2. Townships and Sections were merged with "Union" in a separate Geodatabase before loading into the final Geodatabase. Sections and townships were edited together. Townships were dissolved from sections after editing. 3. The Prescott data came from the more recent Prescott Pilot Project. All other data mostly came from ALP. The Prescott Pilot originates from more recent GCDB data then the rest. The edge of the Prescott with the Kaibab, Coconino, and Tonto did not edge match. Edge matching was done alone the outside edge of the Prescott boundary making it a clean dataset. 4. District Boundaries for the Prescott Project were missing. Prescott District Boundaries were derived from the most recent CFF data. Used the same version of CFF that was used to fill in gapes in the Prescott Project. 5. District Boundaries on the Gila were incomplete in ALP. What District Boundaries did exist in ALP for the Gila were wrong particularly in the area of the Wilderness District. District Boundaries for the Gila were derived fro vintage 11 CFF, the same CFF used in ALP to fill in gaps of data. 6. Wilderness Areas for the Prescott were derived from a combination of Prescott Project data and very recent cartography data. The cartography data comes from very close examination of the actual wilderness legal descriptions. 7. Sycamore Canyon Wilderness has many conflicts in its descriptions. Two of the larger conflicts are labeled as Proposed Wilderness in this data set. The one on the Kaibab is in ALP but may be wrong (Jacks Canyon.) The other one on the Coconino was not in ALP and may not actually be Congressionally designated Wilderness yet but apparently is managed as wilderness by the Coconino. This one was mapped by cartography data in the RO. 8. The boundary between the Gila and Apache Forests along the Arizona and New Mexico border did not edge match. This is probably because the two states have different GCDB data sets. In this data set that line was edge matched using the Arizona or Apache ALP data. 9. The Gila has three locations where Townships overlap each other. Some of them by as much as a half mile. The overlaps were left as overlaps for both Townships and Sections on the Gila for this dataset. The error was clearly an error in the GCDB data that has never been resolved. There were no conflicts with Surface Ownership because of this. 10. Surface Ownership was derived by linking to the ALP database using the ALP CN numbers. There were a small hand full of polygons that did not link to ALP. Mostly because they were missing CN numbers. Ownership for these parcels was derived by comparing with other ownership data layers including older versions of ALP. 11. Most of the Grassland units did not link to ALP. The ALP data for these units appears to be missing in ALP. Ownership for theses units was derived from somewhat older ALP data then the rest. The exception to this was the "Black Kettle" Grass Land unit where a link to ALP was made 12. Many of the ALP coverages had small slivers and gaps. These slivers and gaps were mostly found using the topology rules "Must Not Have Gaps" and Must Not Overlap." An example of these slivers would be where the corner of a rectangular meats and bounds parcel barely crossed over a section line leaving a very small triangular sliver. These slivers were sometimes missed in the editing of the coverages in ALP but became obvious in Geodatabase with topology rules. In most cases it was obvious what parcel the sliver belonged to so theses slivers were merged with there appropriate parcel. 13. Some ALP data had overlapping in Surface Ownership and Section polygons. I all most all cases it was only editing error and the overlap had the same attributes. In only a few cases did the overlap actually need to be reconciled. All overlaps were eliminated except for those in Sections and Townships on the Gila mentioned before. 14. The "Escudilla Wilderness" on the Apache N.F. was not in ALP. The boundary of this wilderness was derived from vintage 11 CFF data 15. The "Bear Willow Wilderness" on the Apache was not in the wilderness feature class in the ALP cover but the line work was. Wilderness area created from line work. 16. The "Columbine-Hondo Wilderness Study Area" on the Carson was not was not in ALP. This wilderness study area was added using Southwester Regional GIS code data. 17. Townships and Sections have a gap on the "Magdalena" ranger district on the Cibola. This gap also showed up in Surface Ownership. The gap was filled as "USFS" owned land. 18. District and Forest Boundary for the "Mountanair" district of the Cibola N.F. were depicted differently in two different feature classes in ALP. The boundary in the ranger_district feature class was clearly wrong so the boundary in surf_own was used here. 19. Some last minute land status changes were made on the Santa Fe National Forest. Because Lands is still working on entering data into the tabular ALP theses parcels do not yet have CN numbers although the line work is from ALP and the ownership is correct. 20. ALP was not consistent with private ownership within wilderness areas. In some areas the private land was cut out of the wilderness and in others it was not. In this dataset we made it consistent by cutting out all private land out of wilderness. There is one place on the "Kachina Wilderness" on the Coconino where this was not able to be reconciled.

Theses five feature classes were refreshed from the original ALP data. Administrative Boundary Proclaimed Boundary District Boundary Surface Ownership Wilderness Surface Ownership was updated by using a Intersect process to bring over the changes. The other four feature classes were refreshed with a manual visual method looking for change.

The derived ALP layers were refreshed. Since the last time the data was pulled from the original ALP the ALP database transitioned from ArcInfo Coverage to Geodatabase. The schemas of the data have changed in that process. Data was copied from the ALP database and compared with the prior derived ALP data. An overlay process using "UNION" was used to find data that had changed. The changes were incorporated into the new derived ALP layers. This process was used to preserve most of the clan up work that had been done on this dataset in the past. In the process we also added more layers bringing the total number of layers to 14. The schemas of the datasets were also changed to reflect the new national published ALP data standard.

The derived ALP layers were updated from the original ALP. Most specifically this update incorporates a corrected Arizona and New Mexico boundary that does not overlap in the two separate States databases.

The Derived ALP layers were updated from the original ALP. Most specifically this update incorporates new data for Tonto and Sitgreaves National Forests. This completes the snapping of ALP to new GCDB for Prescott, Kaibab, Coconino, and Sitgreaves National Forests. There were minor edits to Gila, Carson, Cibola, Prescott, Kaibab, Coconino, and Coronado National Forests in this update.

The Derived ALP layers were updated from the original ALP. Most of the changes are minor. Mostly minor updates to Surface Ownership with the largest change on the Carson. Update to Forest and Ranger District boundary around the Magdalena Ranger Station on the Cibola.

ALP Derived was updated. Apache and Gila snapped to SDI (GCDB), minor updated elsewhere

ALP Derived was updated. Carson, Santa Fe, and Lincoln snapped to SDI (GCDB), minor updated elsewhere
