You can measure altitude level accurately with your mobile without internet connection. Just download this free digital altitude meter App which Turns your phone into an altimeter! (An Accurate Altitude measurement). An app you always need to measure the pressure and height of buildings above sea level.Use this Altitude measurement tool  to measure building heights. Height of buildings from ground level to top floor  may be cannot measure with a GPS  because of inaccurate altitude units.

<b> Question</b>

<b> Is possible Measuring my altitude above sea level accurately ? </b>

I live in a building which sits very high near the top of a hill. I estimate the ground level of the building to be around 700 feet, I live on the 13th floor, so my altitude is approximately 800 ~ 850 feet. I would like to get an accurate measurement (correct to +- 10 feet).

<b> How I did the measurement ? </b>

★ Measure the ground level altitude at a park with digital altitude meter

★ Estimate the height of each floor

★ Using a GPS unit in the flat would produce inaccurate results use digital altitude meter

★ GPS units are inheritly inaccurate at altitude (compared to lateral position)

★ I cannot access other floors other than the one I live

★ I have a good view of the city. By looking at a map, I can accurately calculate my

ground-level distance to certain sea-level landmarks. These landmarks are some 5 km away.

★ I would like to minimize the cost of purchasing special equipment.

<b>问题

<b>可以测量海平面以上的准确海拔高度我？ 的

我住在一个建筑，坐在附近的一个山顶非常高。我估计建筑物的地面是约700尺，我住在13楼，所以我的海拔约800〜850脚。我希望得到一个准确的测量（正确的+  -  10英尺）。

<b>如何，我做了测量？ 的

★测量地面水平高度的数字高度表公园

★估计每个楼层的高度

★在平利用GPS单元会产生不准确的结果利用数字高度表

★GPS单位是在高海拔地区inheritly不准确的（相比，侧卧位）

★我无法访问一个比我住等其他楼层

★我有这个城市的一个很好的观点。通过查看地图，我可以准确地计算出我的

某些海平面标地面的距离。这些标志性建筑距离酒店约5公里。

★我想尽量减少购买专用设备的成本。
