Technical features of the program

I usually go hiking for a few years, and I always relied on trails of the Comunidad de Madrid, grasping the tourism pages and things as well, making screen captures, printing them and taking me them to the trail to make it following it the best that I could, but a few months ago I found WIKILOC, web page that offers you all the trails you want to, and more, and also you can download it to mobile to be able to follow it with GPS of the mobile phone, and I was really completely impressed by the usefulness of such application. I was not lost, had to print maps, had to beat me for hours looking and learning trails, could take Photos, include them and generating a database of my trails, with statistics of all kinds. The panacea, "impressive".

At this point, after making a few trails, I started to think that was missing something, something that really would make that this system was perfect, and that is, a program for PC, fast, (primarily that, to work on the Internet is already well, but is veeeery slow. Or I am ;) veeeery fast), in which I could have all my trails, unlimited trails, (up to 1 million if you want), a database that would allow me to handle them as you would like, sort them, search, include photos, add additional information, and above all, and most importantly so I started this program, that would allow me to edit them, either to correct them (since I always tend to confuse me on the way and I don't want to see that mistake in my trail), and above all to create new trails that could take me. Yes, I know you can do it in other programs, but (one billion buttons) are too complicated, or they are on the web, which makes it slooooow. And, in addition, I wanted to split trails join trails, create waypoints, and above all have the trail in 3D, calculated on a digital model, to have access to the longitudinal profile before to do it. Here below I show you a few sreenshots of the program, and then explain with a glance the most important features of the program.

Well, at first I wanted to create a simple application for me, but the thing was enlarging, enlarging and enlarging and at the end I have created a very comprehensive program to allow all, and when I say everything, is everything (slightly exaggerated :)).

  • Importation/Exportation: Import/export trails to gpx file, including waypoints. Unlimited number of trails, and unlimited number of TrackPoints. Export to gpx, Excel, PDF, XPS and KML/KMZ.

    Import can be made up of 500 trails by selecting up to 500 "gpx" files at the same time.

  • Data table: Very flexible data table that allows sorting by columns, with inheritance of data, attributes, etc.

  • Presentation on map: View on map in accordance with the active trail, which comes from providers of maps, as in "Satellite" mode (photos, orthophotos, etc), as "Map" mode, (Topographic map, street maps, etc). There are up to 20 providers of maps that can be used with the program.

    So, as you're navigating by the trails, in the data table, you're seeing them on the chosen map downloaded from the provider selected, automatically.

  • Digital Terrain Model, DTM: I have downloaded all the files, patches, with elevations of a point every 90 metres from around the world, 16 Gbs, and 30 meters for United States, 7Gbs, (DEM, digital elevation model), taken by a project of NASA, the National Geospatial-Intelligence Agency and the German and Italian Space Agencies, which sent a flight that, relying on terrestrial antennas, took a point each 90m worldwide, and one point per 30 metres to United States.

    The name was given this mission is "Shuttle Radar Topography Mission", SRTM, and to refer to elevations every 90 metres was called SRTM3, (a point is taken every 3 seconds of arc... About 90 meters), and SRTM1, (a point taken every 30 meters, 1 second of arc).

    I've put all these files on a dedicated server that can access all from anywhere.

    And with these files is created the DTM, digital model terrain, and contouring of that we are seeing on the map in that moment, presenting the contour lines according to a configured equidistance, and above all giving the elevation at any point on the map that you pass the mouse cursor, automatically.

  • Longitudinal profile: Profile with direct and reciprocal relationship with the TrackPoints and WayPoints of the active trail. This profile is actually composed of two profiles, one which is which are the points that has been giving by our GPS in field, and another longitudinal profile which is which is calculated on the digital model created, automatically, on the active trail, according to SRTM1 and SRTM3 data. (which I inferred that I have a little imbalanced my mobile phone GPS receiver :)).

  • Edition of trails: this is the mother of the Lamb, and it is the tool more powerful has the program and, in fact, was so started the program, to be able to edit my trails. You can create trails, modify which have, join trails, split trails, clear trails, graphically. If you can join / split / delete, you already have everything, because to edit a trail, it becomes very easy to split my trail at the point where I go out road, again splitting the trail where return to the correct trail, delete the leftover "piece", and join the two "pieces" that have been created, (each "piece" is in fact a trail).

    And the best is that this is done graphically on the map by clicking on the trail in one way easier.

  • Edition of trails. Drawing freehand: I write an individual part for this option, since it is the very best. I've seen (in other programs), when are you going to create trails, you have to go clicking from point to point, and when you go over a road that has many curves, you must click a thousand times to do well the curve or the break, so I created a tool that if you are drawing the new trail, and leave pressed the left button of the mouse, then them will be drawn points each one distance predefined by the user (by default 10 meters), automatically, so you're moving the mouse above the road and you are creating points automatically, becoming much more simple and accurate trail. It is as if you drew Freehand. And when you're done, release the left button of the mouse and creates the last point, ending the Freehand Edition, (and then you can follow point to point, or freehand again). It is one of the things that I've missed in other programs and it accelerate the process of the creation of the trail from 1 to 10, (exaggerating a bit :)).

  • Display/management of photographs: I have created an images viewer so that you can see them easily, rotate them if necessary, but the most important thing is that I have created a tool, to low level, so that they are resized automatically to increase the management speed, with what you will see the photo in its highest resolution and the program will, automatically, that when you manage, move, copy, etc, photographs, it will be done on a version more smaller of the photo, with what this means in speed.

    The photography can "Drag and drop" on one of the columns of the table, from another trail/waypoint or from the files explorer of Windows. And not one by one, but all that you want at the same time, either on the Trail or on some Waypoint.

  • Merging photographs: I have created a tool to be able to automatically merge photos that you take with the program "WIKILOC", on the corresponding WayPoints. You simply have to copy all photos that you've made on the trail, in its maximum resolution, and this tool will merge them to the WayPoints that correspond, and will resize them for their faster management.

  • Compatibility with KML/KMZ files: You can export the trails with photos, the digital terrain model, (triangulation), point cloud with elevations, contouring and their WayPoints to KML/KMZ.

    After export you open Google Earth and you'll have all the information about your trail, and all this without Internet, been it very fast.

  • AutoCAD/Bricscad/ZWCad: Given that I'm an expert in development within CAD platforms, I have curly curl a little, and I have created the program, also, so that works within these three platforms. Thus, you can draw the trails, waypoints, digital model, map displayed, contouring and cloud of points, inside the CAD, with entities of CAD, both in UTM WGS84 XYZ, (that is the projection of the GPS system), as "Cartesian", which is as I have named to another system that does not consider any kind of deformation, nor applies any anamorphosis linear constant, but can be useful for presentations.

    Thus, you can have your trail in UTM XYZ WGS84 coordinates, with what that represents, thus you can include new maps of any active WMS service, (Warehouse Management System), and above all, with CAD tools, you can worked wonders on your trails, terrain, etc.

My intention has been to, always, leave the program completely free, and so is going to be, but the files server on Internet for anyone can see your DTM, contouring and elevations I have to charge it; Since I have to pay the server files on the Internet. I had thought something like 6 euros. I'm sorry, but I can not afford it. So if you want to see the map with elevations, see the contour lines or creating longitudinal profiles of your new trails, (because those that come from other programs already have the elevations of the GPS), to know which will be the slope that you are going to go, you will have to pay 6 euros to gain access to the file server. What I have prepared is, once payment is received, send you a register code that will activate the access to the server, and you will immediately see the digital model on your map. (if breaks your computer, or change your computer or whatever, don't worry that I will give you more new register codes).
