xyLocator

Important Information

Update: Version 2.0.1 is now available (November 2012), for PC and Mac. See installation information below.

  • Note: We recommend NOT using the Windows extractor to unpack the .zip file containing the xyLocator, as the Windows extractor has trouble with complex zip archives and long path names. We recommend using WinZip or 7zip.
  • Prior versions of the xyLocator required the user to download NetCDF .dll files and the .NET Framework.  This is no longer required, as the latest version of the xyLocator is Java-based. All necessary files are included in the zip file (see below), except for the Java installation.
  • Users will need to have 32-bit Java Virtual Machine (JVM) installed on their system before they can run the xyLocator. The 64-bit JVM causes issues with the xyLocator, so if you are running a 64-bit system, please ensure you have the 32-bit JVM installed, not the 64-bit one. Most machines will have the 32-bit JVM installed. Please contact us if you have questions.

EDEN xyLocator is a program for extracting data from spatial hydrology time-series. Data is extracted for specific x,y positions over the time range supplied by the user. The user can also choose among outputs for water stage, water depth, ground elevation (DEM), and days since dry-down (counting from the start of the specified time range).

The user supplies EDEN xyLocator with a tab-delimited or comma-delimited text file. The first row is a header. Each following row is a point position that the user wants extracted from the EDEN dataset. The row must include a position name, x coordinate and y coordinate. Coordinates must be in UTM, zone 17N, NAD83 projection.



 

Installation

Prior versions of the xyLocator required the user to download NetCDF .dll files and the .NET Framework.  This is no longer required, as the latest version of the xyLocator is Java-based. All necessary files are included in the zip file (see below), except for the Java installation.  Users will need to have 32-bit Java Virtual Machine (JVM) installed on their system before they can run the xyLocator. The 64-bit JVM causes issues with the xyLocator, so if you are running a 64-bit system, please ensure you have the 32-bit JVM installed, not the 64-bit one. Please contact us if you have questions.
