Colorado staff and decisions will be made to define improved modeling procedures. The <br />draft from Task 152.1 will be updated to reflect the changes. <br />152.3 Updated Data Flow and Procedures Manual document(s) including actual examples for the <br />RGDSS StateCU/StateMod data sets, and updated RGDSS baseline data sets for <br />StateMod/StateCU, that utilize StateDMl and other current tools. The commands files and <br />summary information about using the commands files will be updated. However, it is <br />expected that State of Colorado staff will update the baseline data set documentation to <br />reflect changes as part of the normal maintenance of those data sets (e.g., during annual data <br />extensions). <br />152.4 Coordinate with State MODFLOW reviewers in order to facilitate inclusion of <br />MODFLOW content to the updated procedures manual and data set examples. The activities <br />will focus on coordination rather than extensive changes to the 152.3 deliverables. <br />Task 155 -Infrastructure Upgrade -Update Java Applications to New Java Version <br />Objective: <br />Update CDSS Java applications to use the latest Java Version (e.g., 1.4.0, to be determined at the <br />time that work begins), in order to address limitations in the current Java version. <br />Background: <br />Updating to the latest Java version will addressing the following issues: <br />^ Java 1.1.8 has been used for over three years and support for this version is decreasing as <br />newer versions of Java have been made available. <br />^ Java 1.1.8 has a number of inherent bugs that have required work-arounds to be <br />implemented. These work-arounds limit the overall performance of the system and <br />complicate maintenance. <br />^ Newer versions of Java include graphical components that can replace third-party <br />components, thus decreasing the number of tools to be maintained. <br />^ Newer versions of Java include features that will increase the overall usability and <br />performance of the system. Examples include: performance enhancements, integrated <br />cut/copy/paste, enhanced graphics drawing (e.g., rotated text, variable line width, mouse <br />hints, batch printing), menu tools, support for PNG image file format, and others. <br />^ Newer versions of Java are better supported by third party tools (e.g., ESRI's Java <br />MapObjects) and therefore these tools can be evaluated as appropriate if existing tools <br />are inadequate. <br />Although the new Java version may require more powerful computers than in the past, the State <br />CDSS users have received computer upgrades recently that will pose few limitations to <br />upgrading the Java environment. <br />
