Layer: Enclosures (ID:1)

View In:   Map Viewer

Name: Enclosures

Display Field: Enclosure_Description

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: Objective: The main objective of mapping the enclosures as lines is to identify which dumpsters have walls that enclose them and which do not. Many of the enclosures were not full enclosures, meaning the walls around the dumpster did not fully close it into a space. With this being said, any walls around dumpsters were counted as enclosures. With this information, it is easy to analyze which dumpsters do not currently have enclosures but could maybe use some. Noting the presence of enclosures can also help waste management teams think about how they want to approach the dumpster while driving a garbage truck up to each one.Equipment: To map the enclosures, I used an Emlid RS2 Multi GNSS Receiver along with a 2 meter pole. I also used a tablet with Arc Field Maps installed on it to actually record the data. Mapping Techniques: To map these enclosures, I used two techniques: streaming and averaging the vertices and then connecting them. The streaming method was used for dumpsters whose enclosures were easy to walk around with no obstacles in the way. While streaming, the device measured points every 1 meter that was walked and then turned all these points into a line after the GPS was stopped. The averaged vertices technique was used for dumpsters whose enclosures were not easy to walk around due to people or things in the way. This technique involved averaging for five seconds at each point of the enclosure, then connecting the dots together to represent the enclosure.Base Station: The base station that would've been used for differential correction was the MTSU CORS Station located on the campus of Montana State University. Since ArcGIS Field Maps was used instead of Emlid Flow in this project, differential correction did not need to be performed.Editing: During editing, the topology of these enclosures was validated to make sure there were no dangling nodes and to ensure that none of the lines crossed over themselves. Due to the length of each of the enclosures, which were only a couple of meters long, there were not a ton of topological errors identified in the editing process.Estimated Accuracy: The estimated horizontal accuracy from this layer is 0.29 meters with a range from 0.16 - 0.67 meters all with 68% confidence. The overall data accuracy for this project is as follows: 0% in the 0 - 5 cm range, 32.02% in the 5 - 15 cm range, 43.86% in the 15 - 30 cm range, 16.23% in the 30 - 50 cm range, 5.26% in the 0.5 - 1 m range, 2.19% in the 1 - 2 m range, 0.44% in the 2 - 5 m range, and 0% in the >5 m range.Spatial Reference Information: The Geographic Coordinate System of WGS 1984 was used to map this data. This corresponds to the datum of D WGS 1984 that was used for the data. The projection of the data itself is in the WGS 1984 Web Mercator (auxiliary sphere) projected coordinate system.Fields: There were two fields in the enclosure data: Enclosure_Description and Notes. The Enclosure__Description field had an open domain that allowed text to be written in to describe how that particular dumpster was enclosed. This allowed the type of enclosure to be noted, most of these domains were written as partial or full enclosures, however, some enclosures were split up from one another which was noted in this field. The Notes field allowed documentation of anything necessary in the field to know about the enclosure. This domain was also an open text domain and only noted when enclosures had inaccessible ends or if there was a bit of a discrepancy between the enclosure and line feature due to alarm sensors.
