Welcome to a continued look at GIS applications involving local government. The focus of this week is on parcel presentation and parcel editing. The goals of this weeks lab were to utilize county property appraisal data to create a parcel report, create a parcel map book, and edit and locate parcels based on specific criteria. The appraisal data was used to identify specific attributes pertaining to the parcel, such as parcel ID, size, location, currently assigned zoning, etc. The parcel map looks at a central parcel of interest as well as all adjacent parcels within .25 miles, using data driven pages to create an index viewing the area in segments (pages).
The initial steps of the lab continued last weeks participation activity exploring county appraisal information. The particular parcel of interest happens to belong to Mr Danny Zuko himself, and we used it as the basis for the map below.
This is just one of the 16 pages created through the use of Data Driven Pages (DDP). DDP is a particularly useful utility when needing to create many different pages of the same map. In this particular frame we are looking at page 10 of 16, which is index number C4. Looking at the bottom right of the page you can see the index overview, with the current page highlighted. Essentially this setup is done by creating an index layer which is built around a base layer. In this case the parcels within .25 miles described above are the base, and the index is created around it at a base scale of 1:2400.The yellow highlights the Zuko parcel. I adjust the base scale to one that has just enough overlap to provide better continuity from one map slide to another. I ended up using a 1:3000 scale. You can see the black lines indicate the different Index boxes, so you have slight overlap with the adjacent cells. The numbers in each of the parcels correspond to the attached map key which is labeled in a table based parcel report (not included). The report was based off of the attribute data table for the parcel layer. The hardest part of the parcel report was adding the zoning data which was not originally included by parcel. The zoning data while boring browns in this map are symbolized by all available zones shown in the legend in the upper right.
After the map book was complete the next portion of the assignment was to combine two parcels, then divide them again using different criteria. Then afterward create a search based on all parcels belonging to a particular owner, and analyzed according to size. The key tasks here were to utilize the data editor and merge the original parcels, then use the feature construction toolbar in conjunction with the editor to create a new parcel from the whole of the merged one. Several useful drawing tools were explored in this activity revolving around measuring distance, drawing parallel to other features, and drawing new line segments based on degree measurements.
This was an excellent continuation of looking at local government data from property data available on county GIS sites to what can be done with it in ArcMap. This was a good look at the tasks actually performed by some GIS analysts daily. Thank you.
