Working with Rhino home range I would use a polygon vector, and the vegetation usage within that home range would probably be represented with thematic raster.

vector data works best for location of camera traps, we use points to map out the location of the cameras and lines for identifying the best route to reach this cameras. for mapping out the territories of cheetahs, I would suggest polygons.
Mine is a vector data, basically getting locations of individual species to access distribution…
I collect vector and raster data. I would like to know forest types and animal types and a type of a road used to visit my nearest nature reserve.
Hi,
I am collecting GPS track of fishing boats to find their fishing grounds. I think its fit for vector. But I am bit confused its under points or line. Also in the end, I have to plot map with region where intensive fishing and where low fishing. But I don’t know how to use this GPS track (GPX files) in QGIS to make map. I tried single track with QGIS. But don’t know how to add multiple and show where intensive fishing.
mine are correcting GPS point of grey crowned crane to find their movement so i think is vector data under point
I’m not sure I understand this topic. My job entails recording data of all my black and white rhino sightings each month (from camera traps, patrols and visuals from hides) and recording all the different areas wherein they occur in order to get an idea of their distribution and use of space in the reserve.
I’m not sure/ I don’t know how I’d go about presenting this data in GIS and would really like to learn in order to bring a more in depth report to my managers.
I would appreciate if anyone would explain these to me in the simplest way possible.
Thank you!
I use both vector and raster geospatial data. We flight drones taking pictures of agriculture fields-raster. From this raster, we calculate stand counts plants-vector. For vectors, we use layers points and for rasters, we use continuous rasters.
Dear Misrak
Location and distance of beehives to boundaries of the wolf habitat are line vector.
''the distance in meters beehive is located from the nearest boundary of the wolf habitat area" is line vector the same as the above.
Lines vector means:Linear two dimensional feature composed of a series of x and y coordinates (vertices)

Hello!
I think they are complementary in making decisions in their study. In the case of vector data, variability and features data such as points, lines and polygons are stored, for example, if you want to record a sample station on sightings of some animal species, those stations would be your points. On the other hand, raster data gives us information about reality, for example. elevation, soil type, vegetation type. By this, I mean that if we put together the information obtained, we could obtain a better analysis.
Thanks!

I currently not have any project going on but I am practicing with CTD results obtained online to see how the illustration of water quality such as temp, salinity and etc work in QGIS. So, I guess that I will be dealing with the raster data since they are continuous data
Vector data I collect are GPS coordinates of households, landing points, centers of barangays (villages)
Raster data I collect are thematic such as seagrass bed type or mangrove forest type
In my hydrogeological field, i think locations of wells, depth to groundwater at each location will be vectors, while topographical and geological map of the area will be raster. However, the choice of representing the data as a raster or vector depends on the purpose of the investigation.
I have GPS locations where the samples were taken and this would be vector points.
my collected data is represented by both vector and raster spatial data models, vector point for monitoring animals movement on sightings or camera traps, and raster data for vegetation. it is a tricky question though, still a little confused.
For a potential project, I will most likely need to collect both vector and raster data. My vector data would be represented in points (GPS points and camera trap locations) and also in lines and polygons (animal movement tracks from GPS collars and their home range). The raster model would present land cover (especially vegetation and urbanization in the selected area), and of course, it would also include the Open street map for the selected location, or maybe even aerial photos. Here, too, continuous and thematic types of rasters would alternate.
to Monitor home range of a bird, raster image would be best, to monitor nest of bird, vector image would serve best
I don’t currently collect data, but I have used vector data before with IUCN data about species distribution. I still don’t really understand raster.
I will use both Vector and Raster. I will be using a point vector for the river sampling sites and also for landmarks, points of interest et. I will use vector polygons to represent areas common to flood. I think that I could use a thematic raster for areas of invasive species such as Hymilain Balsam providing the landcover class includes invasive species and the grid/pixel size is small enough to show the detail down to say a 3m square.
I use both vector and raster layer for my project. A line transect survey of birds. To get the breeding point of birds, a polygon vector would be used. Also, when vegetation site are included in the survey a raster data model is used.
