A task memorandum describing and summariziDg Task 1.06 activities and results. <br /> <br />User Involvement <br /> <br />I, Two meetings with users to discuss spatial data requirements and database design, <br /> <br />2, Briefing Room demonsttations to users of spatial database ca.pabilities. <br /> <br />Respo.usib.ility <br /> <br />Luis Garcia will be the Task Leader. <br /> <br />Work Plan <br /> <br />Subtask I, Populate the spatial data (this applies to data types identified in Task Memorandwn 1.06- <br />I). Different sources of spatial data for particular data types were reviewed in Phase I. and the <br />information was cross-referenced with !be model requirements (spatial resolution, precision, <br />projection, etc.) in order to select the best source of data: c:,,, ... <1/..

Finalize the dacabase design. The design will take into account the need for data access <br />and 5CJ:een and bard copy display of spatial data. The spatial database design and construction will <br />utilize ARClINFO BS the GIS software to import data but win lISe the GIS software GRASS for <br />modeling and data viewing by tbe user. <br /> <br />Subtas" 4, Install GRASS 4,1 on the 8GI and port and update existing GRASS 4.0 functions to <br />GRASS 4.1 on the SGI in a library fomla!, <br /> <br />Subtask 5. Performance of quality control cbecks on sp~ data as the database is populated, <br />Quality control procedures will include displaying of multiple data layers overlaid with one another <br />tl) chc<:k for proper gco-registration and spot chccl;ing of a few individual data values in ellcb data <br />Inyer, The use of these data in modeling tasks will provide additional quaHly coutrol. <br /> <br />Suhtask 6. Develop spatill1 data access procedures. A simple visual displny tool using a GUI will be <br />developed to enable the user to display point, line, and raster data using the OIS software GRASS. <br /> <br />SubtBRk 7, Develop DMls to retrieve data stored in the relational dlllabllSe (pbysical characteristics, <br />station, and historical) corresponding to 1000ations displayed in the vi.uw display tool. <br /> <br />Su!'lt.a~ 8. Produce hard copy maps. Produce approximately 20 bard copy color maps (not to e1l:ceed <br />three different types) in an estimated size of 24" x 36". for u..e in the user/public involvement <br /> <br />.ulJ QJ,/~J1I <br /> <br />2-21 <br />
