Entry Requirements
Using SuperMap iDesktop software to configure one (or more) flat map, free topic selection, works content is not limited, based on a variety of data sources through data processing and mapping expression means to create a thematic map with characteristics of style. This category does not involve development, and the ability of geographic information processing and visual expression is comprehensively investigated.
-
Software Requirements
-
Either SuperMap iDesktop.Net or SuperMap iDesktop Java, the version must be higher than 9D (2019) SP1
-
Data Requirements
-
the data used in the entries can be the map data published by the country or the relevant organization, or the big data or other source data provided by Internet enterprises。
-
in order to ensure the security of geographic information and safeguard national sovereignty, security and interests, contestants are required to ensure the legitimacy of data sources and have the right to use and issue data accordingly.
-
Mapping Requirements
-
Attractive and professional map with strong visual appeal. Map is a graphic expression of geographic information. In order to achieve better information expression, map must have strong visual appeal.
-
Map display is smooth. The performance of map display affects the user experience directly, and the display speed of the process is one of the important indicators of the map.
-
The contents of maps shall conform to the provisions of China's relevant policies and laws. World maps and national maps involving the national boundaries of the People's Republic of China shall fully represent the territory of the People's Republic of China. For example, the map of China must show the important islands in the South China Sea, such as the Diaoyu Islands, Chiwei Islands, and draw the boundaries of the islands in the South China Sea with corresponding symbols.
Submission Criteria
-
Submit the original data and processing data (generated in map making process).
-
Submit data description documents in .PDF format, including introduction of original data (such as data source, data content description), introduction of result data (such as layer explanation, meaning of attribute field);
-
Submit all maps you made (as .JPG or .PNG format).
-
Submit mapping report, including data processing notes, mapping process notes, and map performance optimization notes (optional).
-
Submit attractive screenshots (at least three) (as .JPG or .PNG format) and an instruction video (no more than 15 minutes, with subtitles in English, need to be uploaded to YouTube).
-
Submit a self-evaluation document of the work by the instructor. The document is submitted in .PDF format (Requirements: concise and clear; 100-200 words). If there is no instructor, no need to submit.
-
All the files required need to be submitted as compressed files in .ZIP format to Dropbox.
-
Structure of submission files:

Mapping Process Reference
Mapping process below is only a suggestion:
-
Data preparation
-
convert vector data in other formats into SuperMap data format;
-
query and copy data, and make data preprocessing;
-
vectorize images data.
-
Data processing
-
conduct topological check on vector data and correct errors;
-
fuse vector data and fusing small or mini objects;
-
extract the data through resampling;
-
obtain data of other specified types through type conversion;
-
obtain buffer range of data through buffer analysis;
-
isolines and isosurfaces are extracted from raster data.
-
Map rendering
-
preset points, lines and filling symbols, which are produced by the symbol editor;
-
set styles for layers;
-
make thematic maps to achieve richer styles;
-
optimize label display effect through label avoidance and labeling along the line.
-
one dataset can be added to the map many times, such as the road layer. Different display styles can be configured. The display scale can be set to control the display and improve the display effect of the map.
-
the layer grouping function can be used to uniformly manage the layers of the same map.
-
Functions of map browsing
-
cancel map editing, selection, capture and other states;
-
fixed scale can be set for the map;
-
set the display scale for layers, which not only conforms to the drawing specification, but also can be hidden when unnecessary to improve the browsing performance;
-
different display scales use data of different scales, with fewer data nodes of smaller scales and higher browsing efficiency.
-
balance between aesthetics and performance through anti-aliasing control of layers.
-
with the performance diagnosis function of SuperMap iDesktop, I searched for poor performance layers, analyzed the reasons and carried out optimization processing.
