Delivers Groundwater Management Tools

Project Manager for Planning IS/GIS
Santa Ana Watershed Project Authority
and the SAGIS 2 Project
SAWPA's newest project, called SAGIS 2, will create water management tools for use by SAWPA, its member agencies, and others managing groundwater. SAGIS 2 will utilize the existing available databases and provide tools utilizing ArcView GIS, ArcView Spatial Analyst, ArcView Dialog Designer, and ArcView 3D Analyst.
These tools will simplify
the connection between well location information and detailed groundwater
data, allowing point and click availability of analysis and reporting
tools by users who are not trained to use ArcInfo. Packaging these tools
as loadable extensions with a common interface increases the power of
ArcView GIS to simplify complex and repetitive tasks.
The tools give experienced ArcView GIS users or Avenue programmers useful documented utilities they can customize for their own organizations. The project will build these tools grouped by task and in phases over approximately one year. SAWPA will make the tools available to member agencies and stakeholders on a continuing basis.
Scope, Management, and Funding
Project funding comes from SAWPA's member agencies so the next step was to discuss the project with these agencies. Member agencies and stakeholders provided excellent feedback on the draft. The scope was refined to better serve their current and future needs. A stakeholders' meeting was held to discuss the concepts and provide a prioritized list of tools.
Because this project is resource limited, the schedule must take into account existing projects, the support of our member agencies, and staff availability. Resource-limited scheduling differs from deliverable deadline scheduling because the budget remains constant. With a constant budget there are two variables: time and staff. When scheduling for resource-limited projects, the completion date is determined by considering staff availability and task effort.
In contrast to resource-limited project scheduling, deadline-driven project scheduling requires managers to add staff as needed to accommodate the deadlines. Commercial software developers and consultants frequently use this type of scheduling.
As part of the planning phase, "make or buy" determinations should be made. The "make or buy" determination is a careful analysis of the organization's ability to accomplish all needed tasks to complete the project. SAWPA has determined that most tools will be developed in-house and that outside consultants will probably be used for development of the database connectivity portion of the tool, described later.
Member agencies provide most of the project funding as part of their continued commitment to properly manage groundwater data in the watershed. Funding discussions with stakeholders who are not represented by one of SAWPA's member agencies or are outside the watershed have been initiated. Additional funding or rescheduling of other staff activities may be required to accelerate completion of project tasks according to schedule.
Extensions to ArcView GIS?
Stakeholders include member agencies that are familiar with GIS and water districts and departments who do not have any GIS capabilities. By utilizing ArcView GIS and the SAGIS 2 tool set, both groups receive maximum benefit. Users with sophisticated GIS personnel and skills will be able to accomplish routine tasks with greater speed and consistency. Users with little GIS experience will be able to quickly perform analysis and produce maps and documents with minimal training. Additionally, as the skills of these new users grow, they will have coverages, data, and all the power of ArcView GIS to create their own analyses and applications.
Extensions can be loaded into any ArcView GIS project making all the scripts and special interfaces available to the user without additional loading or complications. In addition, the extension will have a main control panel providing easy linkage to all features of the tools, as shown in Figure 2. Extensions can be unloaded when no longer needed, freeing up memory.
SAWPA has located the wells in the basin based on a number of methods. The California State Well Number contains approximate positional information, and many wells are located on watermaster maps and district maps. SAWPA and its member agencies are also locating wells using GPS technology.
