I am doing a very simple tasks: I have data with long\lat information and I am using Display X/Y data in ArcMap to display them first in ArcMap, then export it to a geodatabase as a feature class. The problem is the data is huge for me: 7 millions records with about 20 fields. It takes me about 3 days to complete the task of display X/Y data, then when I tried to export the displayed X/Y data, it crashed so far as I tried. I wonder how I should deal with big data in ArcGIS? ... View more

I need define a projection system for the county map in Utah. I will first define counties.shp files by selecting a predefined geographic coordinate system and then the UTMutah projection. A custom coordinate system, UTMutah has the following parameter values. I need display XY data of Utah hospital, but even if I use the same projection UTMutah as counties.shp. They are far away each other, not correctly in the same spatial extent. I attached the counties.shp and hospital cvs data. Could you please let me know which step I am getting wrong?

I'm using coordinates from as CSV file and using Display XY data, however when I do it, the points are far away from other layers and are only visible at a scale of 1:1 as opposed to 1:300,000 for everything else. I've check the source and tried to use the project and define projection tools. ArcGIS says they're all using the same system and everything is practically identical. Is there a known way to fix this? Is it something wrong with my data? ... View more

I'm using the textbook "Getting to know ArcGIS" to learn ArcGIS. I am working on the first exercise of the Chapter 15: Use a created hyperlink to images related to objects within an attribute table. I can get this working fine using absolute paths however I'm getting problems when I try and use relative paths. When I try and open a hyperlink from a relative path I get a message saying: Unable to open "E:\EsriPress\GTKArcGIS\Chapter15\Data\cabbagetown1.jpg" Please make sure the path is correct and the document exists. My images are contained within a folder called "Images" and this folder is in the same folder as the mxd. I've been using this website to ensure I have the correct relative path for my images. I've tried different ways of pathing to my images, but I keep getting the same error. I've tried putting the relative path in the hyperlink base option of map document properties and in the attribute and neither is working. Also I have store relative pathnames to data sources ticked on. Although I'm not sure if this makes a difference if I'm not moving the mxd. Does anyone know why I am getting this error and how to solve it? ... View more
