Name: Dumpsters

Display Field: esrignss_receiver

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Objective: The main objective in mapping these dumpsters as point data is to show the exact locations of every dumpster on the campus of Montana State University. These locations include points on the football field and athletic facilities, the main campus, academic buildings, the dorm areas, the dining halls, student housing, sports fields, parking lots, and other buildings associated with MSU such as the police department and the Plew Building. It is important to note that the MSU farms a few miles off campus were not mapped in this project. This data is important because it can help the waste management team identify locations of all dumpsters on their routes. With turnover in waste management staff, there were a few dumpsters getting left behind on campus; hopefully this map can help mitigate that issue. This data can also help anyone on campus find the nearest dumpster if they need to throw away trash. Dumpsters move around each time they are picked up and emptied by garbage trucks, so these locations may vary a bit based on this. However, they should not ever move more than a few meters from the location in which they were mapped. It is also important to consider that some of these dumpsters may be temporary, mostly those in and around the football field. Since this data was mapped during football season, there is likely an abundance of dumpsters in that area to account for high traffic, but this may change after the season ends.Equipment: To map the dumpsters, 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 dumpster points, I used an average positions techniques where I stabilized the GPS on the pole for five seconds at each dumpster location. I recorded the location of each of these dumpsters right upon the front end of each dumpster; however, I also gathered offset distances and azimuth angles for each dumpster in case I want to represent this data at the center of each dumpster since I did not physically get in the dumpster to record its central position. Since the dumpsters shift each time they are picked up, I determined it was not necessary to offset each of the points just to map the center of where the dumpster was when I mapped it because these points will be constantly changing so exact precision like this is not needed.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 topological analysis, it was ensured that all dumpster points were within the polygons of the dumpster pads and did not intersect with any dumpster enclosure lines. As stated before, offset azimuths and distances were measured for each dumpster point, however, the points were not moved during the editing process since the dumpsters move around each time they are emptied. Therefore, the exact center of each dumpster was not necessary to map, so each of the points represent the front sides of each dumpster on the sides where they open up.Estimated Accuracy: The estimated horizontal accuracy from this layer is 0.22 meters with a range from 0.11 - 2.39 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 are multiple fields for the dumpster points: Enclosure_Status, Ranking, Offset_Az, Offset_Dist, and Notes. The Enclosure_Status field has domains of Yes or No. If the dumpster had any sort of walls that enclosed it, whether that be a full enclosure or just partial, it was marked as "Yes" and if it did not it was marked as "No". The Ranking field has five domains: Excellent, Good, Acceptable, Poor, and Terrible. Each of these domains describes the condition of each of the dumpsters, with Excellent being the highest ranking and terrible being the lowest. To help with this ranking, there is a picture of each dumpster that is attached to every point. The Offset_Az and Offset_Dist fields have open domains where any integer can be entered to represent the angle from where I measured the dumpster to its center and the distance between where I measured each dumpster to the center of each dumpster. The Notes field has an open text domain and in that field, there are some instances that I ran into while mapping these dumpsters. Some of these include dumpsters not having a distinguishable dumpster pad, dumpsters possibly being temporary, or dumpsters being partially on one ground material and partially on another.
