"surface features" - Translation from English to Arabic

..but the surface features still recall a time when they were rivers and flood plains - evidence of a long oceanic period before the Red Planet lost most of its water to space.
لكن ملامح السطح لا زالت تستذكر زمناً عندما كانت أنهار و سهول مغمورة دليل على فترة محيطية طويلة قبل أن يفقد الكوكب الأحمر

It is also aware that the generation of an analytical model, be it that described by means of contours on a chart or a mathematical expression, results in the generalization of line and surface features at various scales (Fox and Hayes, 1985).
كما تدرك أن توليد نموذج تحليلي، سواء النموذج الموصوف بواسطة كنتورات على خريطة بحرية أو كمعادلة رياضية، يسفر عن تعميم سمات خطية وسطحية بمقاييس متباينة )Fox and Hayes, 1985(.

11. It was noted that, given the capability of microwave radiation to penetrate clouds, ERS provided all-weather images of the Earth’s surface and allowed the monitoring of surface features even in areas where optical instrumentation failed because of frequent or permanent cloud coverage, such as over equatorial and polar regions.
١١ - وذكر أن سواتل ERS ، نظرا لقدرة اشعاع الموجات الصغرية على اختراق السحب ، توفر صورا لسطح اﻷرض في كل أحوال الطقس ، وتتيح رصد معالم السطح حتى في المناطق التي تخفق فيها اﻷجهزة البصرية بسبب كثرة أو دوام وجود السحب ، كما هو الحال في المناطق الاستوائية والقطبية .

In addition, remote sensing can aid in the identification of sea surface features, which can include variables such as ocean colour (indicative of concentrations of phytoplankton), temperature, and sea height.

12. The assessment excavations followed established forensic archaeological procedures, including the establishment of a datum, and the examination and recording of surface features and contours, with some necessary modifications (see Manual on the Effective Prevention and Investigation of Extra-Legal, Arbitrary and Summary Executions, 1991, United Nations).

The multi-spectral nature of most satellite images allows the identification and discrimination of a wide variety of surface features as a consequence of their distinctive responses over different regions of the electromagnetic spectrum (ranging usually from the visible to near-infrared, short-wave infrared, middle infrared, thermal infrared and microwave regions).
٦٤ - تتيح الطبيعة المتعددة اﻷطياف لمعظم الصور الساتلية تحديد وتمييز مجموعة واسعة من السمات السطحية نتيجة لاستجاباتها المتميزة في مجالات مختلفة من الطيف الكهرومغنطيسي )تتراوح عادة بين المجال المرئي والمجال دون اﻷحمر القريب والمجال دون اﻷحمر القصير الموجة ، والمجال دون اﻷحمر المتوسط ، والمجال ذي الموجة الصغرية( .
