Any suggestions for the best projected coordinate system (in meters) for the Southeastern US, particularly the state of Florida (entire state), coastal Georgia, and coastal Alabama and Mississippi? ... View more

I am creating a survey for sea turtle surveys, and I have repeated fields for each animal. There is weather/sargassum patch information associated with each turtle that is captured. Often multiple turtles are captured in the same sargassum patch and under the same weather conditions. Is there a way to frame a calculation statement so that the weather/sargassum information can be automatically carried over to the next entry (from the first in a list of repeated fields) to save time in the field? The way I currently have it produces an error because it's a circular reference (photo attached). Ideally, I would like the second observation (turtle) to default to the first, but I am not sure how to code this or if it's even possible. Thank you! ... View more

Here's a fun little challenge. I have point locations of snakes, and I need to extract the habitats associated with each point from a land cover raster. Problematically, the points were taken along roads, not within the actual habitats in which the snakes were spotted. I would like to extract the values of the raster cells nearest the "Road" cells without modifying the land cover raster (it's 20GB). Currently I am just zooming in to each point and doing this manually, but thought there might be a way to do it more quickly. Thanks for the help! ... View more

I am running a hotspot analysis on polygons assessing spatial clustering of decreases/increases in the population size of a particular bird (the increase or decrease is the weight, I am using the CONTIGUITY_EDGES_CORNERS Conceptualization of Spatial Relationships). Problematically, I have two polygons with zero nearest neighbors (no overlap, edges/corners touching--think islands). The optimized hotspot analysis runs without any issues, and one of these islands emerges as a significant cold spot. Are these results valid, or should I exclude these polygons from the analysis and only use contiguous polygons? Thank you! ... View more

For example, if a field tech is monitoring the same animal over a time-series can the field default to the same animal ID as the previous record? ... View more

Hi all, Many of my agency's mobile data collection has thus far been accomplished using the Fulcrum application, but a few our of groups requested switching over to Survey123/Collector. In Fulcrum, I typically design the app and then import an ESRI Shapefile of point locations. These point locations show up on a map in the app and users can navigate to a point, click it, and enter all of the survey information they need. I am looking for a similar set-up/user experience with Survey123 (or possibly Collector), and it is important to have repeatable nested fields (users collect vegetation species data along with percent cover of each plant species). Designing the app in Survey123 seems simple enough, but I am struggling to understand how I can attach location data to each record (we have hundreds of points to visit), visualize the points on a map, and navigate to the points as we do in Fulcrum. If anyone has any advice I would appreciate it! Thanks in advance! ... View more

I have three habitat metrics (bathymetry, distance to seagrass, distance to mangroves) at different locations and would like to create a (Euclidean) similarity matrix. ... View more
