The project OPTIMAP is a joint initiative of the BGIC, the GSSAC, the DGFI-TUM and the IAG. The main goal of the project is the development of an operational tool for ionospheric mapping and prediction. The software uses geodetic observation techniques that are sensitive to the free electrons within the Earth*s ionosphere (GNSS, satellite altimetry, radio occultations, and DORIS) in order to provide representations of Vertical Total Electron Content (VTEC) with high spatial and spectral resolution. Since these observations are distributed rather unevenly over the globe, a so called Two-Level-Model (TLM) strategy has been developed, a combination of global and regional models. The additional incorporation of solar observations enables a reliable forecast for upcoming ionospheric conditions in terms of VTEC. In this contribution, we present the high-resolution VTEC products of the TLM, a correlation study of solar parameters and VTEC and the first results of the forecasted ionospheric conditions.
