The array of archival maps from the 19th and 20th centuries is very large and, in order to assess their reliability for a particular analysis, some kind of evaluation form must be used. The proposed evaluation form comprises both formal and quantitative criteria, enriched with the maps’ elaboration circumstances, which may influence their reliability. These factors are also applied at both the spatial and attribute levels of information. Guidelines include: the scope of content, the map’s mathematical precision, the descriptive information correctness, the time reference of the content, and the information transfer efficiency.
The crowd-sourcing approach should be implemented into a new historical geoportal of Poland due to its increasing potential in WebGIS. Registered users will be able to acquire spatial data from various map series. As it requires feature class harmonization, a common symbol classification should be proposed. It will be based on chosen topographic maps of Polish land from the 19th and 20th centuries. Feature classes derived from archival maps will be standardized and reclassified, but with no information lost. This will be done in four steps which require: data acquisition, map content harmonization, feature class typification and attribute table elaboration. In addition, four methods of data harmonization can be distinguished: symbol sequence, semantic analogies, spatial relations and a combined method. The paper covers the elaboration of two thematic layers - roads and railways based on three topographic maps (Austrian 1:75 000, German 1:100 000, Russian 1: 126 000).
The article has two main goals. The first is to present the theoretical foundations in the field of cartographic sources editing, and the second is to discuss and present proposals for the model digital edition of old maps on the example of the Gaul/Raczyński map from the early 19th century. The most important questions concern relations between editing cartographic and written sources, differences between scientific and popular map editions, the role of digital tools in editing, differences and dependencies between map editing, cartography and historical map, and – finally – problems of sustainability of digital projects.

Artykuł ma dwa zasadnicze cele. Pierwszym jest przedstawienie dotychczasowego dorobku teoretycznego w zakresie edytorstwa źródeł kartograficznych, a drugim omówienie i prezentacja propozycji modelu cyfrowych edycji dawnych map na przykładzie mapy Gaula/Raczyńskiego z początku XIX w. Najistotniejsze pytania, na które autor poszukuje odpowiedzi, dotyczą m.in. relacji między edycją mapy a edycją tekstu, różnic między naukowymi a popularnonaukowymi edycjami map, roli narzędzi cyfrowych w edytorstwie, różnic i zależności pomiędzy edycją mapy a kartografią i mapą historyczną, a także – na zakończenie – problemów stabilności i utrzymania cyfrowych projektów.

The aim of the article was a comparison of the content’s scope, classification and presentation methods on topographical maps issued at the turn of 19th and 20th century covering the territory of former Russian partition. Three of such maps were chosen for the analysis, namely: Russian (scale 1:84,000), Austrian (scale 1:75,000) and German (scale 1:100,000). As a starting point of the study served an attempt at reconstruction of map legends, as, a coherent symbology key (i.e. map legend) can be found neither for Russian nor German map. It was conducted by employing the symbology keys prepared in the Interwar Period, as for the Russian map there was no legend enclosed, while in the case of German the legend enclosed featured only the road network. Apart from the legends, an analysis of the map sheets covering four areas was conducted. Those areas were, as follow: Brest, Dęblin, Pinsk and Pułtusk vicinites. The next stage was to elaborate a legend comparison with summary in the form of a table for particular thematic layers: settlement and built-up area, transport network, sacral buildings facilities and other buildings, land cover, hydrography, relief, and borders. An assumption was made that despite the apparent similarity of the scales (1:75,000, 1:84,000, 1:100,000) and source materials the maps analysed are distinct in terms of presentation of the geohistorical landscape. The settlements on the Russian map were illustrated in a schematic manner, while the other maps approached the subject more meticulously. The discrepancies involve also such areas as: road network, land cover, and waters, which were categorised along different sets of criterion. It happened that some categories present on the Russian map were absent from the Austrian and German. It involved such objects as: fascine roads, wooden churches or radiostations. Those differences stem from not only the “military mode” of elaboration of the German and Austrian map, but also conscious interference in the scope of content and classification methods.
The aim of the paper is to propose a data model for editing historical records using the example of Karol Perthées' works from the late 18th century. These consist of cartographic sketches, elaborated on the basis of parochial questionnaires and the maps of palatinates of the Crown , which are at a scale of 1:225,000. The model links the advantages of direct source data representation with scalability and flexibility features, which provide analytical possibilities. The sketches are indexed using the INDXR application and the structure of the model reflects the structure of the source. The maps were analyzed in a GIS environment, but no georeferencing was performed. The data collected separately as symbols and annotations were treated independently and were linked via features. The model is illustrated by a preliminary study of materials covering the area of the Zemborzyce parish near Lublin.
