Mapping software with sensor data visualisation

We created a radiation detection sensor with a gps built in. We want to visualise the data we created on a map after the sensor is back. Sensor and gps data is stored on the detector and can be downloaded as .txt or .csv file to a computer. The string is flexible: In the moment we have a header with semicolon separated and the data also semicolon separated with nl on the end. The software should: - run on windows pc or in a browser - map data from google, open street map or custom map tiles - visualise the data from the sensor and gps via "wrong colour track" on the map - colour auto scaling to the highest reading, 10 colours - red is highest - visualise optional as heat map - show a trendline from the recorded track via time and sensor data - when mouse over trackpoint on map, show time, position, speed, altitude, direction, number of sattelites, sensor data - possibility to enter data like mission data, name, lokation and export pdf with relevant data and map screenshot - store the "mission" on the computer to be visualised whenever needed - export the "missions" on flash drive to be presented on an other computer with same software We plan the software developing, depending on customer needs.
