QGIS le Fundy Footpath Örnek Haritası oluşturmak

Fundy Path

The Fundy Footpath is a wilderness hiking trail located along the Fundy coast of New Brunswick, Canada. It is a charter member of the UNESCO Fundy Biosphere Reserve and affiliated with the NB Trails Council Inc. and the Trans Canada Trail. The Footpath takes hikers through the coastal Acadian Forest, home to the world’s highest tides, old growth forests, and several rare and unique types of flora and fauna.

The trail was created, is maintained, and promoted by a group of volunteers known as the Fundy Hiking Trail Association Inc. (FHTA)(1975). As a non-profit organization the FHTA raises funds for its activities through the sale of guidebooks that include a trail map. In 2011 I approached the FHTA to volunteer to update the official trail map. As a volunteer creating a map for a non-profit organization QGIS fit the bill as both a tool for editing data and for final map layout. Through the efforts of myself and members of the FHTA the new official map of the Fundy Footpath included with the guidebook was created from start to finish with QGIS.

Proje

QGIS te yeni bir Fundy Footpath haritası oluşturma işlevi üç parçaya ayrılabilir:

  • Veri toplama

  • Veri düzeltmek ve hazırlama.

  • Harita üretimi.

Veriler hem GPS aletinden hemde çeşitli ücretsiz kaynaklardan elde edilebilir. Örnek veriler(kamp alanı koordinatları, gelgit kesişimleri, örnek eksenlse gibi) Garmin GPSMap 60CSX le elde edilmiştir. Bu veriler GPS eklentisi kullanılarak GPS verisinden QGIS shapefile türüne dönüştürüldü. Sonra vektör türündeki ücretsiz veriler `Natural Resources Canada (NRCan) CanVec den elde edilmiştir<http://geogratis.cgdi.gc.ca/geogratis/en/product/search.do?id=5460AA9D-54CD-8349-C95E-1A4D03172FDF>`_ website and from Service New Brunswick (SNB) online.

Nihai harita ürününde kullanılacak verileri hazırlamak üzere belirli görevleri yerine getirmek için QGIS içindeki aşağıdaki araçlar kullanılmıştır:

  • GPS ile toplanan veriler düzenleme araç çubuğunu kullanarak temizlendi.

  • NRCan ve SNB’den elde edilen vektör verileri bir araya getirilmiş, sorgulanmış ve vektör araçları kullanılarak nihai harita alanı için kırpılmıştır.

  • A comma-separated file obtained from SNB was imported to QGIS as a point layer using the Add Delimited Text Layer plugin, the Interpolation plugin was used to create an elevation raster that was then used to create a hillshade raster and elevation contour layer with the GDAL raster tools plugin.

Once the data required to create the map was assembled and in a usable format the creation of the final map was started. To create the hiking map data was symbolized and labeled with the symbolization properties dialog and labeled with QGIS’s very functional label engine. Once labels and symbolization were in place the map composer tool was run to create the layout. It was very easy to add useful map elements such as a custom north arrow and elevation profile in the print composer. Two layouts were created since it was to be a double-sided map. Once both layouts were created they were exported as PDF files and sent to the printers.

Sonuç

The hiking map was printed on heavy-duty waterproof paper, folded and inserted in the back of the new edition of the Fundy Footpath Hiker’s Guide Book. QGIS was the best and most functional choice for the creation of this map. Being free software the price was right for a volunteer creating a map for a non-profit organization. But the real advantage of QGIS was that it had all of the functionality and tools required to create a highly useful and detailed hiking map from start to finish. I would highly recommend QGIS to both experienced and beginning GIS users alike.
