current VHGT parsing

loadland.cpp

        esm.getHNExact(&rawHeights, sizeof(VHGT), "VHGT");

        float base = rawHeights.heightOffset;
        int currentHeightIndex = 0;
        for (int y = 0; y < LAND_SIZE; y++)
        {
            uint8_t delta = rawHeights.heightData[currentHeightIndex];
            currentHeightIndex++;
            base += delta;
            landData->heights[y * LAND_SIZE] = base * HEIGHT_SCALE;
            float scratch = base;
            for (int x = 1; x < LAND_SIZE; x++)
            {
                uint8_t delta = rawHeights.heightData[currentHeightIndex];
                currentHeightIndex++;
                scratch += delta;
                landData->heights[x + y * LAND_SIZE] = scratch
                        * HEIGHT_SCALE;
            }
        }

thanks for info & hint
