EnviroForensics staff members have the experience and capabilities to fully meet clients’ database management and geographic information system (GIS) needs. GIS, with versatile analytical capabilities, used in conjunction with Computer Aided Design (CADD), has become one of the most powerful resource management tools available in the last decade. Data stored in the GIS reveals complex spatial relationships that govern planning decisions. The most important key to successfully applying GIS in a project is applying the analytical capabilities.
Database Management
EnviroForensics staff members have developed relational databases using Microsoft Access to track and maintain environmental and analytical data. The database can use separate tables to track sampling stations, individual samples at each location, and analytical results for each sample. The database can also be used to track sample location information such as northing and easting for use with a GIS system. Data reporting is generated directly in the database. Tabulated results are output via hardcopy or electronically without using additional applications. Graphical results are also generated directly in the database for reporting purposes or for decision-making. Graphical or tabulated results are generated on all data collected or on specific subsets of data (such as data collected since a specific date). Data modeling is also accomplished within or with the use of the database.Most data modeling or statistical calculations do not require the use of other programs to generate results.
GIS Mapping and Modeling
GIS technology manages spatial data, such as maps, linking the data with quantitative information through a computer database. The resulting electronic map is “intelligent,” able to respond to queries with an analysis of spatial interrelationships of the stored information. Characteristics of relations, such as sphere of influence, resource multi-use access road nets, interdependency and compatibility can be analyzed by GIS and displayed either as a map or as a table of quantitative information. A major use of GIS relational analysis is exploring the outcome of various approaches, allowing planners and managers to select different management options and variables, and to observe the simulated interactions of each alternative option.
