1. What is ASCII Reader Extension?
ASCII Reader is an Extension to import table-like text data as dBASE tables into ArcView. The data can be separated by tokens, multiple spaces or exact width. Multiple tables can be imported as one single dBASE table or as multiple dBASE tables.
Since version 2.5 ASCII reader also supports import of netCDF-files (a data format used for meteorological data) in CDL notation.
Since version 3.5 ASCII reader also supports import of OVL ASCII files (like generated from TOP50, Geogrid Viewer or Garmin GPSTrans)
2. System Requirement:
- ArcView 3.x
3. Installation:
Just copy asciireader.avx to your $AVEXT-directory (something like c:\esri\arcview\av_gis30\ext32)
Activate ASCII Reader in the Extension dialog (Program|Extensions) and open a new view.
ASCII Reader adds a black button in your View GUI with the red letters "ASC".
4. New in latest versions:
- 3.0: Extended netCDF support now (max. three dimensions)
- 3.1: Fixed two bugs in netCDF import: Supports variables of type "double" and field names > 10 letters now
- 3.2: Parameters for field width and precision can be defined now
- 3.3: Fixed some bugs caused by empty fields
- 3.4: Better handling of default values; minor bugfixes; added source filename to each record
- 3.5: Implemented import of OVL ASCII data. The module was tested with GPS data from a Garmin GEKO, imported by the program GPSTrans
- 3.6: OVL import creates point and line shapefiles now instead of dbf tables.
