I am conducting a habitat suitability analysis using ArcGIS desktop 10.2.2.
I have a vector .shp of a number of georeferenced hare sightings across Ireland, however when I load the layer on to my map, the map will only show my existing layers (island of ireland, approx 1:2,000,000 WGS 1984), or alternatively I can 'zoom to layer' on my new vector, which causes the other layers to disappear but the new polygons to correctly draw, at a scale of something absurdly high, around 1:500,000,000,000.
I have tampered with the 'scale' function to rescale the polygons, but it only seems to make the scale get even larger.
I have toyed with various projections too, but to no avail.
Anyone have any ideas how to reconcile these two?
