PUBLICATION OF DATA FROM THE LATVIAN REGIONAL HYDROGEOLOGICAL MODEL LAMO4
Abstract
Geographic information systems (GIS) are based on the approach of displaying data from individual layers, where a manageable number of geospatial objects are displayed within a single layer. The entire content of a hydrogeological model (HM) can only be partially included within this framework. HM input data and modeling results as layer surface maps are a way to easily, clearly, and simply publish the model content and simulation experiment results. However, this approach is not sufficient for regional HMs. Regional HM data may be of interest not only to specialists in hydrogeology and state environmental monitoring services, but also to any citizen of the country who owns real estate or land; anyone who cares about the environment and ecology. The three-dimensional nature of HM data and its high density make it difficult for users who are interested not in the overall model maps but in the HM data for a selected location to access when information is published in layers. No GIS can automatically provide such summaries, and their a priori structure is not designed for this task. The Groundwater Vistas modeling environment also does not provide such local summaries. The following describes the extraction of hydrogeological data for each individual location in the territory of Latvia, its mathematical processing, and the publication of the summarized data in the WEB environment.
