hey, i have a csv file with coordinates X Y and Z values.
i want to convert this csv file into feature class and get the points.
also , i wanna color the area of each group of points that varies by depth.
You can do this in one of several ways.
Open the Geoprocessing menu (Analysis Group -> Tools), enter search text, "XY Table to Point" and fill in appropriate fields, click "Run".
Once the point feature is loaded into the Contents pane, Open the symbology menu and select option in the top drop-down to Symbolize your layer by Unique Values. Set the value field to your field containing depth.
Then you can either use an attribute query (cumbersome) or if you are looking to create basic points, you can dissolve them by attribute. Using the dissolve tool and setting the tool to dissolve the points by attribute will give a unique set of points based on each unique attribute value. However, the dissolve tool will make it to where the all the points that share that unique attribute value will dissolve into one unique record pertaining to that attribute value.
The only other alternative, since you are using depth, is to use the Aggregate Points tool(GeoAnalytics). This may help identify points based on created polygons with common attribute values.
Help topics provide other information.
and there are tutorials on most topics in the help files
as well as symbology
