We have a requirement for 2 x Office based GIS staff, each of whom who will need to service the data exported by a team of surveyors capturing cycle features. Postings will be at our offices in Harwell (Oxon). The project will last up to 6.5 months and starts on 1st July (we may allow for commencement on 7th July). Remuneration will be £12,500 for the duration of the project but the positions may run for less than 6.5 months. GIS STAFF TASKS: Each GIS staff member will process data for their team of surveyors, of which there are 5: TASKS for each GIS Staff member: 1. Import data into QGIS (.osm and GPX track) 2. Check imported data from field against UK Map, photos, video, GPX track, google where needed and notes from survey team 3. Correct data, the attributes in the database and the position, form, assignment of each geographical element (points and lines) 4. Merge and Export data CHECKING THE DATA: Checking the Data is based on these principles: 1. Querying the database to see if data is missing, and check against the photo, video and notes supplied by the surveyors to fill those gaps in the database AND to check if those features have the correct attributes. For example, a cycle sign might have the wrong attributes and this would be discovered when checking the video and the pictures supplied by the surveying teams. The idea is that every single feature must be checked to have all and above the correct attributes. 2. Carry out a graphical check to see if the asset is indeed recorded on the map as a point OR line, if it is positioned correctly on the map based on the background info like UK Map and Google, or aerial imagery. If errors are found in the position of the features, video and pictures must be checked and the correction applied to UK Map. We need to make sure that a point does not carry the attributes of a line and vice versa (mistakes happened in the field). 3. Then correct them if necessary and also use video (with GPX files) and photos (geo-referenced) supplied by the survey teams. So this is all about checking and correcting the attributes and the graphical feature, because at the end TfL want’s GIS files (shapefiles) which will show the position of the features captured in the field (with a 95% accuracy) and the attributes for those features (with a 95% accuracy in this info). QGIS PROCESS: When the GIS staff have accessed the data import, checked and corrected it, they need to split the info into 2 layers, line and point, check and correct the data, merge data at the end of day which has been collected from all members of their survey team and make sure it does not overlap (for example 2 surveyors may pass through the same intersection and both of them collect data for the same feature) or is duplicated. So in summary, the GIS staff - import split into 2, check and correct and merge. QGIS Process in Detail: 1. Import of data (.osm + GPX track + geo-tagged photo layer) 2. Split .osm data in 2 layers (line and point) and assign a style for a better visual impact 3. Overlap UK Map and other sources (aerial) 4. Check and correct the data (both for attributes in database and graphical elements inside map), based on UK MAP, photos, video, GPX track 5. Merge data (all 25 point layers and 25 lines layers) at the end of day which has been collected from all members of the processing team and make sure it does not overlap (due to the fact that surveyor may come across an intersection surveyed by another member of the same or different team) or records duplicated features (for example 2 surveyors may pass through the same intersection and both of them collect data for the same feature). 6. Merge data at the end of 5 days of processing in order to deliver to JMP for checking 2 large layers. This is necessary because otherwise it will be needed 1 day to merge and check (if errors in merging and correct them) 125 point layers and 125 line layers (25 layers a day x 5 days) Please respond without delay to: Marcus Ambler Director Mfatech Limited 1 Toomers Wharf, Canal Walk, Newbury, Berkshire, RG14 1DY Tel. +44 (0) 207 871 1332 Mobile. +44 (0) 7917 829 360 Email.
