How are your mushrooms located? Do you have geographic coordinates for them? If so, you could use Google Earth or Google Maps. If you have lots of mushrooms to tag and you have that sort of information, you can use products like ArcGIS which can join spreadsheets like Microsoft Excel or .txt files to representations and use the coordinate structure. If you have a version of the map that can be processed in something like R, you can also plot points based on positions. In short, there are many ways of plotting this sort of information. All you have to do is be able to georeference the positions of the mushrooms relative to the map you have.
the answer depends on the cost of the selected solution.
For a free solution, Google earth is a good solution. You can create files with kml extension that are read by Google Earth (you will find Matlab softwares in Matlab File Exchange that convert lat/lon data to google-earth files).
If you have more money, you can use GIS software such as ArcGIS.
You can subsribe to an ArcGis OnLine account for free and upload directly tabular files with X,Y coordinate columns (cf this link for bolete map in Europe)
I would definitely use QGIS, eventually with the openlayer plugin if you want to have a "known background" such as google maps. For administrative layers of your country, you may want to look at www.gadm.org
Any mapping software would suffice the requirements. You can use open source desktop mapping software like Quantum GIS (QGIS), MapWindow GIS for the purpose.
Any GIS software should work. You can use the freely available QGIS (Quantum GIS) or the suite SAGA GIS. If you can have access to ArcGIS, I would suggest it because the graphic interface is nicer.
Junaid Khan: I suggest that you can use the Software Quantum GIS and gvSIG is a free version of GIS (GIS Software Libre). Quantum GIS use I recommend you install the plugins "open layer" and access Google maps: physical, satellite providers (best known cloud maps as Google Earth, Bing Maps, OpenStreetMap, etc.) that will serve as reference coordinates or just plot points, polygons and lines. If you are interested please see the links I offer. Best regards. Dr. de la Colina Rodríguez
U can use free software as QGIS, GRASS, GOOGLE EARTH ALSO TRIAL VERSIONS OF MAPINFO, GLOBAL MAPPER, SURFER... THEY ALOW MANAGING FORMATS FOR EXEMPLE U CAN DO A MAPPING WORK WITH GOOGLE EARTH AND SAVE IT AS KML FILE AND THEN U CAN OPEN IT WITH GLOBAL MAPPER THEN EXPORT OT AGAIN TO SHAPEFILE OR OTHER
QGis is an open source that can help you doing the maps. However, if you like an easy way to collect data about Mushroom in the field, using your mobile phone, you can follow my advice, see:
It depends upon the scale of work that you're doing. Do you want to do work in the field, mapping the precise location of macrofundi stands in the wild? If so you'll need a program that permits you to get precise GIS coordinates that can be uploaded. ESRI's new Survey123 is one alternative. So, too, is the relatively inexpensiveGPSKit. They work with IPhones and IPads. Alternately, an inexpensive GPS tool (like the ones hikes employ) can give you the lat/long of precise locations. Just be sure to get a GPS (like Garmin's that permits you to upload locational data. That can then be downloaded and entered into one of the programs like ArcGIS or QGIS, etc.
If, however, you just want to map general areas of macrofundi growth then you can probably just draw into the mapping program using a polygon, circle, or other draw tool. So ... a little more information on the work you want to do would help us give you better advice.
This exercise requires inventorying using a GPS unit. Each location will be saved as a waypoint. Most GPS units have simple software which allows you to display your points on a map.
Thanks Tom Koch, yes I want to map the precise location of macrofungal stands on a map. I have GPS co-ordinates for my collected specimens but I have no idea how to use these in a software like arcGIS or QGIS.
