Abstract: The article studies the use of GIS and DB to analyze text and cartographic materials of the information systems “Memory of the People” and “Memorial” and non-digitized materials of the Defense Ministry’s Central Archive to identify soldiers accounting for inexact data and data about those missed in action (after being wounded). The key element of the studies is the adjustment of the Great Patriotic War archival maps of the portal “Memory of the People” and a resource of the American Association of Historians “Gutenberg” to functionally use them in GIS and geoportal. The research methodology is the following techniques: step by step studies starting from a supposition through data search to a hypothesis, its test with the help of specialists and individual search for supporting documents with the aim to further perpetuate the memory of the fallen. The scientific component is the creation of database complexes covering the Great Patriotic War maps and those of the prewar periods as well as geocoded data, the formation of the regiments’ configuration, the cross-matching of data of reports on those lost, documents specifying the losses, memory books, financial statements, etc. The research novelty is the complex use of data of the Great Patriotic War maps, both old and modern ones, as well as data of the database “Memory of the People” and “Memorial” and other documents stored in the Defense Ministry’s Central Archive with the application of GIS, DB and authors’ software for cross-matching. The main conclusion is the efficiency of GIS and DB in search of data of those wounded soldiers who are considered missed in action.

Abstract: The article studies GIS and geoportal adaptation of multi-sheet plans of mid 19th century territories. The authors have revealed a layer of complexes of multi-sheet large-scale cartographical works of the mid 19th century presented in the form of territory plans on certain locations. One complex of 65 sheets belongs to Vetluzhskiy Uezd of Kostromskaya Guberniya. Other guberniyas can also boast such complexes. The plans demonstrate the boarders of landownings, populated regions and areas. To create various raster electronic maps the authors have suggested to use a method based on the evaluation of parameters of the sheet grid followed by virtual combining of plan sheets and formation of the agreed complex of raster electronic maps with preset parameters. They suggest to use raster electronic maps for geocoding the list of populated territories. The main conclusion is the possibility to use this approach for creating databases with raster electronic maps covering multi-sheet complexes of mid 19th century territory plans which can be further employed in GIS or geoportals when computerizing historical studies. The creation of such databases will add existing information resources covering large-scale topographic boundary maps of 8 guberniyas made by A.I. Mende and military topographic maps thus expanding research opportunities.
