つい先ほど、NASAのPerseveranceローバーが約7か月かけて3億マイルの旅を経て火星に無事着陸しました。このMostly Mappingマップ・オブ・ザ・ウィークでは、最新のJavaScript APIを使用して構築されたカスタムアプリを紹介しています。このAPIは非地球ジオイドをサポートしており、正確な測定と位置特定が可能です。<\/P>

Loved the app Bernie and very timely with NASA's accomplishment to land "Percy" successfully. Couple of suggestions to pass onto the authors...app wouldn't start in a Chrome Browser but was fine on Firefox...I don't know if Opportunity and Curiosity's driven paths were supposed to display but they weren't showing up for me. Otherwise I had fun exploring Mars!
Working fine in Chrome for me. Awesome work guys!
I tried the compare option. I live in the desert and realize that perspective is very different in such wide open spaces and without usual landmarks we can be thrown off. I will further explore. Thanks for the exploration.
This worked with Chrome for me, but when I get that moment when Chrome doesn't want to, Firefox works. I didn't have to resort to Firefox this time.
So cool! I'm amazed at the resolution. I do wish it had a scale bar; it's impossible to tell the scale, of course, and I definitely like that there's a measuring tool, but a scale bar would be more convenient. Anyway, thanks for sharing this!
