<div style='text-align:Left;'><div><p><span>This metadata describes the mapping updates of stereocompiled building roofprints feature of DRCOG Denver Region Urbanized Project Area. The feature was compiled from DRCOG 2016 Orthophoto Mapping. This 1"=100' scale imagery is comprised of 4-band RGBIR color orthoimagery with a GSD (Ground Sample Distance) of 0.5'. Imagery was collected with a Vexcel Ultracam Eagle aerial sensor. Imagery is projected in State Plane Coordinate System, Colorado central zone using the Lambert Conformal Conic map projection parameters. Horizontal and vertical datums are NAD83(11) and NAVD88(GEOID12A) respectively.</span></p></div></div>

Capture criteria: Only permanent structures are captured. Collect buildings with area >= 48 sq. ft. and over 5 ft. in height. Arms and indentations should be 2.5 ft or greater are captured. Canopies, carport covers, and sheds are included. For multi-level commercial/industrial buildings, capture each level as a unique record IF the building is >= 1000 sq. ft. and the multi-level roof levels are >= 400 sq. ft. in area and over 5.0 ft in height. Each polygon is a separate record. Polygons that are part of the same building have a matching building ID. For pitched roofs, collect the highest point to get the building height. The lowest point will be a common lowest point if multi-level.

Compliance with the collection and accuracy standard was ensured by the placement of GPS ground control prior to the acquisition of aerial imagery. A softcopy aerotriangulation adjustment is performed on the aerial imagery is Leica XPro software. Accuracy of the stereo compiled features is a function of the aerotriangulation accuracy as summarized by the X, Y, Z RMSE statistics of the ground control points.
Completeness is ensured in the final vector editing process by comparison to the 2016 digital orthoimages as a backdrop to the building roofprint vector features.
There are no Attributes in this data set.
The horizontal accuracy of the delivered Edge of Pavement (EOP) lines features is a function of the aerotriangulation accuracy as expressed by the X and Y RMSE statistics of the ground control. DRCOG stated accuracy requirement (AppendixB_Feature Requirements_20151002.xlsx) is National Map Accuracy Standard (NMAS) for 1"=100' scale mapping. NMAS accuracy for map scales larger than 1:20000 horizontal tolerance is 1/30" for 90% of well defined points or, 3.0' horizontal accuracy. RMSE of the control is X = 0.138' and Y = 0.148'.
The Horizontal_Positional_Accuracy_Value was tested in accordance with Geospatial Positioning Accuracy Standards Part 3: National Standard for Spatial Data Accuracy (NSSDA), FGDC-STD-007.3-1998. NSSDA horizontal accuracy is 1.7308*RMSE_r or 1.7308*0.202 = 0.35'. NSSDA Horizontal accuracy of the aerotriangulated aerial imagery meets or exceeds the NMAS requirement of 1/30" for 1"100' scale mapping.
0.35
The vertical accuracy of the delivered Edge of Pavement (EOP) lines features is a function of the aerotriangulation accuracy as expressed by the Z RMSE statistics of the ground control. DRCOG stated accuracy requirement (Appendix B_Feature Requirements_20150806_notFinalized.xlsx) is National Map Accuracy Standard (NMAS) for 1"=100' scale mapping. Vertical NMAS accuracy for map scales suitable for 2' contour mapping is defined as one half the contour interval or 1' for 90% of well defined points. RMSE of the control is Z = 0.085.
The Vertical_Positional_Accuracy_Value was tested in accordance with Geospatial Positioning Accuracy Standards Part 3: National Standard for Spatial Data Accuracy (NSSDA), FGDC-STD-007.3-1998. NSSDA vertical accuracy is 1.9600*RMSE_r or 1.9600*0.085 = 0.17'. NSSDA Vertical accuracy of the aerotriangulated aerial imagery meets or exceeds the NMAS requirement of 1' for 1"100' scale 2' contour mapping.

the map editing process performs the same two functions for the planimetric and topographic data, which is; 1. to check the data for accuracy, and 2. make the mapping more aesthetically pleasing and easy to work with. The various map features are assigned unique digital layers according to Kucera's general layering scheme (or a more "custom" layering scheme if specified by the client). "Layering" meaning the separation of like features to a unique digital level that can be viewed, located, counted or otherwise manipulated to the exclusion of other features/levels. Planimetrically, a good example of the layering system would be that all of the major buildings such as houses and commercial buildings be placed on their own layer named something like "BUILDINGS" so they can more easily be viewed or worked separately from more inconsequential structures such as small storage buildings or sheds that would be own their own layer named "MINOR BUILDINGS" or whatever the client would like those particular layers named. Other planimetric examples of the use of layering would be the use of separate digital layers to differentiate paved roads from unpaved roads, treelines from brushlines, ditches from streams, etc. The finished mapping is then usually gridded, the appropriate title block information is added (info regarding the scale, contour interval, mapping location, client name, date of photography or Lidar collection, etc...), translated from Kucera's in-house editing software - primarily VrOne - into the digital format and layering scheme requested by the client (usually AutoCAD and/or ESRI) and delivered to the client on a DVD or by means of electronic delivery (email or posting to the FTP site for the client to download).

Editing of compiled features takes place in VrOne environment. Editing consists of layering validation, duplicate point removal, trimming lines, closing of polygons, etc. Vectors are compared to ortho product to validate geometric accuracy. All compilation is cut to project boundary. Where building polygons that intersect project boundary the buildings are left whole.
