Especially newer Windows users have no idea over the command line tool cmd. The Graphical user interface (GUI) is only what she know. The most computations on a computer are not viewable in the GUI and the most computer tools have no GUI. The command line is the direct using of a computer without a GUI. Not every computer program has a GUI, just exiftool. Open the command line tool in Windows via the Start button and search for cmd and open it. Immediately after inserting the exiftool command in the command line tool (cmd), which was created by »GPS Geotagger Simple«, the command starts. Immediately. Instantly. Directly. At once! An editing of the command code must be realised in the textarea in the webpage. By editing the command code in another editors it is possible to lost the encoding of the code and the command will fail.
First of all, it should be mentioned that the exiftoll file must be renamed from exiftool(-k).exe to exiftool.exe. The exiftool is a command line tool. It works simply with the command exiftool when the command line tool is in the same directory as the exiftool.exe is storaged. In other cases the path to the exiftool.exe must be prefixed like: C:\the\path\to\exiftool.exe. The functionality of exiftool is really widespreaded. Go on the webpage of exiftool for download it and learning more about the possibilities: exiftool.
The reason why original photos should not be used is not the insecurity of the »GPS Geotagger Simple«. Many more things can happen that can destroy a photo file during the editing process, such as a power failure and many more failures. If originals are used, then a possible loss is purely your own fault.
The loading of files into the webpage is not a upload and includes not a upload. An upload requires a form element with specification of a URL to which the data should be sent. The style of the buttons of an input element is the same as that of a form element. However, in »GPS Geotagger Simple« there are only input elements and no form elements. So in »GPS Geotagger Simple« default there is no upload. However, there is a possibility of modifying the »GPS Geotagger Simple«.
To avoid useless load on the map servers, no maps are loaded at startup. There are 5 different maps to choose from. Please be careful with the choise of the maps.
The security restrictions of the browsers do not allow to read the full locale file path. For the displaying of the photos and for the creating of the exiftool command is the full locale file path needed. There will not be send to everywhere except inside the browser.
The »GPS Geotagger Simple« is only testet with JPG files (photos). The ExifReader and the exiftool can handle more than JPG.
The »GPS Geotagger Simple« can default read only single or multiple files or single directorys without subfolders inside. However the most browsers can read single directorys with subfolders inside. The »GPS Geotagger Simple« is not compatible for this. This is a matter of the arrangement of the »GPS Geotagger Simple« as "simple".
For the creating of the exiftool command is the full path to the storage location of the exiftool.exe are needed. There will not be send to everywhere except inside the browser. Only the full local path without "exiftool.exe".
It is posibble to use own exiftool commands. This commands will be added in the commands text by every command line of each photo file. They exists many of exiftool commands to manipulate the EXIF data in a photo. The default functionallity of exiftool makes a copy of the original files as FILENAME.JPG_original and manipulate afterwards the FILENAME.JPG. The »GPS Geotagger Simple« generates exiftool commands that includes the command -overwrite_original and with this exiftool makes not a copy of the original. For this and other cases please use only copies of photos and never the originals. More information and more commands are listed on the exiftool webpage.
The box for the photo list is default a little bit small in the height. This is due to the design of the webpage and under consideration of smaller monitors. The list box is vertical resizeable. In addition it is possible to hide (toggle) a few of boxes in the sidebar via the ↓↑ button in the top right corner. For furthermore space use the browser fullsize mode with the F11 keyboard key (toggle). Last but not least it is possible to use the zoom in the browser (Ctrl and - or +).
Anyone is allowed to download the »GPS Geotagger Simple«, use it locally and modify it. The possibilities of modification are widespreaded.
The simplest modifying of the »GPS Geotagger Simple« is to use it local and save the path to photos and exiftool.exe. For this it is necessary to set and save the value of the input box.
<input type="text" id="imagepathlocalid" class="imagepathlocalclass" value="C:\my\privat\path\to\my\privat\photo\folder" placeholder="C:\path\to\photo\folder">.
<input type="text" id="exiftoolpathlocalid" class="exiftoolpathlocalclass" value="C:\my\privat\path\to\the\exiftool" placeholder="C:\path\to\exiftool\folder">.
Please consider that its only the path in wich the "exiftool.exe" is saved and not a path with included "exiftool.exe"
A multiple selecting of photos for set one coordinate to all selected is possible. It is a little bit complex and not »simple« and for this reason not included in the »GPS Geotagger Simple«. For a better workflow without that expanding of the script it is possible to activate the keyboard shortcuts in the script code.
For the "▲" and "▼" pager buttons and the "SET" button there is a keyboard shortcuts function included in the »GPS Geotagger Simple« and by default disabled.
An example of modifying is the loading of directorys with subdirectorys inside. The corresponding HTML code is already prepared:
<input type="file" onchange="inputfileload(event)" webkitdirectory multiple>.
In the modifying use "webkitRelativePath" (webkitEntries) to read the relative paths of the subdirectorys.
It is possible to modifying the »GPS Geotagger Simple« for using Google Maps & Bing Maps or other maps. For this it is necessary to expand the choice of the map in the script code for the OpenLayers map loading. For both its a personal API Key necessary.
For the display of the current photo there is a function included in the script to dislpay the photo in a map with zoom and move, but the performance of this is not so good. For the display of the current photo you can include a script that use CSS to make it zoomable:
For the display of the current photo you can include a script that use canvas to make it zoomable:
Simple Pan and Zoom Canvas
Please attention for modified »GPS Geotagger Simple« that are not modified by yourself. It is possible to modify it to a dangerous tool.
The precission of GPS is dependent of the position after decimal point. The OpenLayers uses a mathematical endless precission, because it is calculated by the pixels on the monitor. In the most cases in OpenLayers the GPS coordinates are rounded or fixed (truncate). The dimensions of the map is a stretched form, because the earth is no flat or quadratic. The displayed maps are created from peoples on computers via satellite photos. The satellite photos are not 1:1 to the real ground on the earth and deformed to fit the map. There are tolerances in all of this. In addition, it should be noted that although the earth is round, but also noncircular. Last but not least, the longitudes are very close to each other at the poles and very far apart at the equator. This also affects the precission in a screen map. Because of the stretched form of the map, the precision is very accurate at the poles and less at the equator.
The »GPS Geotagger Simple« fixed (truncate) the GPS coordinates to 6 digits after decimal point. This is a average precission of theoretical/mathematical 0.1 meter. When using the map, it becomes visible that the markers are not always very accurate. This has many technical reasons. The whole thing can't be done without a certain amount of tolerance.
The table shows a average precission.
