Prior to the start ofthis project, it was discovered that some ofuu key uataseto would be available <br />for use in this mork-, After discussing the mo�juu with cwcu partners a was clear that some entities had <br />data that could hu useful w their duumo were acquired, These duumowent through u Quality c^ntr^| <br />(Vc) process m determine issues such uo the usability ^cthu data, verifying the data completeness, and <br />reviewing the spatial uuuuvmributimu^omnp|umnss^m`duoomuriomeo, <br />After the QC process was completed, the data was organized into folders and assembled into the <br />GIS, The CWCB is using ArcGIS.R' Version 9, so the data was assembled in ArcMap.R', Naming <br />conventions for the ohupumuo and attributes were developed mmake future cus query / identification <br />/ <br />analysis hr the cwcu staff easier, Parcel polygons and easement polygons that existed in the spatial data <br />were matched to scans of the paperwork that documents these features, and the spatial data was attributed <br />with their appropriate information, <br />In the case where there were paper documents but n^ spatial data the documents needed mhu <br />converted into spatial representations inucusformat, This was accomplished hr using Coordinate <br />Geometry (cocm)^entering the bearings and distances that are found in the description m create the <br />easement polygons, The Assessor's parcel data was pretty much current m`do^mp|uu^wn^pmxaohudm <br />be created, The easement data that was cono`dhr Planet nmIR'� was tied m the Arapahoe County parcel <br />data m ensure u match m the parcel data, <br />Data from TsT Infrastructures were converted from xomcxo.R' drawing files mssa| R'ohupumuo <br />and were not adjusted spatially mmatch the parcel data, <br />Task 3 — Linkin2 Pamir Records to the Soatial Data <br />The third task of this pro�ject involved linking the scanned documents with their spatial <br />representations and attributed the parcel measement polygons with necessary information,xrcMap.R) <br />utilizes u process called '4mu1inaing` that will link u file mucusfeature. In this project the scans were <br />stored as PDF files, so these PDF files were linked to their appropriate polygons, Certain pieces of data <br />were extracted from the scans and were entered uo attributes within the easements, These attributes <br />included the date ^c the document, the cost ^c the easement (if u,muh|u)^ the date ^c the recording, the <br />reception or book and page information, the expiration date, and who the easement was with, <br />After this process was completed there were still some easements without scans, and a list of these <br />easements were provided m the cwcustaff, Likewise, there were parcels from the Arapahoe County <br />Assessor's data that did not have links m scanned documents, In some cases the parcel geometry did not <br />match the descriptions and in other cases the scans were not complete for all ofthe parcels, The missing <br />easement and parcel polygon data were addressed in Task 5, <br />Task 4 — In-Depth Data Analvsis and Data Review <br />After all of the parcels and easements were created and linked with the documents in hand, and after <br />all ^cthu attributes that were created were checked, an in-depth analysis ofthe data was performed mmake <br />sure that the data w represented was correct and complete, xu part ^c this task, any missing information <br />(scans ofpaper documents or spatial representations ofparcels or easements) were identified, TsT <br />Infrastructures had most, ifnot all, ofthis missing information so the CWCB staffasked TST Infrastructures <br />for this information mhu used in Task 5. <br />���� <br />Task 5 — Fill in Missing Information <br />After the list of missing information was generated a was determined that the TsT Infrastructures <br />data should help mbring the database vrm-dam, This data came m Planet msIR'wxomcxo.R'Drawing <br />files (DWG files), Planet GISIR' created ESRI.R' shapefiles ofthis data and incorporated them into the <br />project, Each easement polygon created by Planet GISIR' was matched to the TST Infrastructures data and <br />vice-versa, If any data was missing it was created and attributed, After all of the missing easement <br />polygons were created and attributed, they were linked m their scans w was done in Task s <br />When the missing information was completed, ufinm| review was performed mu all ^cuu data m <br />help m ensure that the database io current and complete, uu"ouu was created for the duuouo created hr <br />Planet cusIR' (Easement Polygons, Pro.juot Line Features, Project Point Features, and Pro.juotPolygon <br />This docummupresentouusndingsaepouuvehisproject. This report and live demonstrations <br />of the GIS environment will be given m audiences identified by the CWmotaff. <br />As the CWCB moves forward with this project and data, the maintenance and upkeep of the <br />documents and data will need to be addressed, The simplest way to keep the data current is to require any <br />new easement requests to contain an AutoCAD.R' Digital Exchange File (DXF) or an ESRI.R' shapefile of <br />the easement, This spatial data should huin State Plane Coordinates, Colorado Central Zone, mxom <br />Coordinates, and os Survey Feet, This io the predominant coordinate system ^cthuduuouo used inthe <br />project, uu"ouu should hu created for all ^c the submitted data, To keep the scanned documents similar, <br />they should hu provided uoueoFfile, Upon approval ^c the easement the documents will hu recorded u <br />the County Clerk and Recorder's ocoou, This recorded document should hu the one contained in the eoF <br />and whose geometry io represented in the ozF file mohupumu, <br />To make the attribute maintenance easier, each spatial feature contains only a unique identification <br />number (ID), This |oio used m link the feature mu spreadsheet omumningun^cthuuo*hominfo,mutimu, <br />This way a will »u easy for the nvcu staff m keep the tabular information current. <br />The parcels owned by the CWCB were easily identified in the Assessor's parcel data and seems to <br />hu pretty complete, There io still m` issue linking these parcel polygons m scans ^c their deeds, In some <br />cases the parcel geometry did not match the descriptions and in other cases the scans were not complete for <br />all ofthe parcels, The Assessor's parcel maps were downloaded (and included in the deliverables) for use <br />in helping midentify them, but the boundary lines ^c individual parcels and tracts were not included in the <br />spatial parcel data — only their outer boundaries are represented, <br />
